Identifying a Class 6 GSA Red Label Container
First, let's determine how would you identify a class 6 GSA Red Label Container. Safe identification can accomplished by identifying the external parts of the GSA container listed. Class 6 container drawer fronts will overlap the edge of the container body. If we look at the label on the control drawer, it will indicate to us wether we have a red label or black label container. Red label containers will have a silver label with red lettering, indicating that the container was manufactured after October 1990.
Is a Class 6 GSA Red Label Container safe opening really that difficult? It is not if you identify the safe properly, have the right safe tools, and use safe opening techniques which are appropriate for this type of safe.

Safe Opening by Side Drilling or Top Drilling
Safe opening by side drilling or top drilling safes can often be the most efficient of safe opening methods. Other than safe lock manipulation, front drilling is often the preffered method of safe opening. When a safe lock failure requires that the safe be drilled, it does not necessarily mean you must approach the safe opening from the front. Safe opening by side drilling or top drilling may be your best safe opening method, depending on the safe lock and the construction of the safe. Advancements in safe technology and safe construction methods, such as glass, difficult hard plate, effective repairs, or additional relocking devices often make front drilling extremely risky and not a recommended course of action in opening certain safes. To not know what is between you on the outside of the door and the safe lock case is an open invitation to disaster and almost certainly a recipe for a difficult and complicated safe opening, rather than the efficient, professional safe openings we prefer and take pride in.
The recommended safe opening procedure for many high security TL-15, TL-30, TRTL-30, TL-30 x 6 or better safes is often through the side. It is often possible to side drill a safe and penetrate the safe lock case without touching any glass and setting off any relockers. Safe openings can be performed where relockers are pinned to prevent firing and the glass allowed to break. This is often the best safe opening method if there is no access to the top or side of a larger safe. However, drilling a safe with glass that is broken as part of your safe opening procedure will require that you replace the glass in order to repair the safe back to its original condition, and it may be difficult and or costly to replace the glass plate in many higher quality safes. Additionally, you will save much time in your safe opening procedure by not having to devote time to drilling for the relockers and pinning them to prevent firing. Your efficiency in safe opening allows you to offer more competitive rates for your valued customers and avoids any loss of security of the safe itself when you have completed your repair in a cost effective manner.
In most cases the only damage to a safe in a side drilling safe opening is the hole itself, which can be plugged and repaired in a manner which is more secure than the original construction of the safe. You must have a safe opening procedure which includes the penetration itself and an understanding of what is between the side of the safe and the safe lock case.
Side drill safe opening or top drill safe opening methods
1. Side drill to view the change key hole with your scope.
2. Side drill to penetrate the side of the safe lock case and view the wheel pack.
3. Side drill to punch the lock bolt into the safe lock case.
4. Side or top drill to cut off a lock bolt or compromise the boltwork of the safe.
Unlike front drilling safe openings, where you drill into the safe until you reach the safe lock case, side drill safe openings may require exact measurements. If you are going to drill into the side of the safe to scope the safe lock through the change key hole, you must determine exactly where that change key hole is relative to the side entry hole. For your depth measurement, you can remove the dial and insert a thin stiff wire into the spindle hole, alongside the spindle until it hits on the case of the safe lock. Add about 1" more to accomodate the thickness of the safe lock case, and another 1/2" to allow for clearance between the safe lock and the cavity between the safe lock case and door cover. Add your measurements and measure that same amount from the front face of the door, at its edge, back along the side of the safe. This is good for the depth measurement. For the elevation measurement you must determine the handing of the lock and its position (right hand, vertical up, vertical down, or left hand.) If you don't determine the handing with references or by making an educated guess, using the safe handle orientation and position, you may be drilling more than one hole.
Safe opening measurements for the safe lock change key hole
1. If the safe lock is installed vertical up, the change key hole will be 1/2" down from the dial center and 1/2" to the left.
2. If the safe lock is installed vertical down, the change key hole will be 1/2" up from dial center and 1/2" to the right.
3. If the safe lock is installed right hand, the change key hole will be 1/2" down from dial center and 1/2" to the right.
4. If the safe lock is installed left hand, the change key hole will be 1/2" up from dial center and 1/2" to the left.
Some safes do not provide a change key entry hole in the back plate of the safe lock case. There may not be enough clearance between the safe lock back cover and the door cover material to insert your scope, even if there is a change key hole. In cases like this you can drill into the side of the safe lock case and view the wheel pack of the combination lock. It is also possible to drill the lock bolt away or compromise the boltwork if you can view the boltwork arrangement with your scope and the design of the safe allows this safe opening method.
Side drilling a safe and viewing the change key hole with your scope requires that you make an alignment of the wheels, taking notes of the numbers as you read the dial. Safes with Sargent & Greenleaf safe combination locks have the #3 wheel closest to the drive cam at the rear of the lock. When viewing the wheels through the change key hole you can either scope the change key entry hole in each wheel or scope the gates. The wheel gates are much easier to find. Make a mark on a dial ring 41 numbers clockwise of the opening index. Whenever a gate appears through your scope hole, note that number on the mark on your dial ring. This a working combination number which you can later dial to the opening index. Determining the gates in the number 2 wheel and the number 1 wheel is more time consuming because the number 3 wheel will obstruct your view. You must constantly advance the dial very slightly to move the #2 wheel around, but always return to the #3 wheel to open your window of view through the gate. After you determine your number for wheel 2, you will have to place both wheel 2 and wheel 3 at their respective numbers every time you advance wheel 1 to determine its number. While it is possible for one safe tech to scope the change key hole of a safe lock, it is much easier for two safe techs, or one safe tech and a good camera. If you are good at dialing you can concentrate on which wheels you are moving at all times and can do it alone. Unless you have really long arms this safe opening procedure makes a camera very useful and quite indispensible. It can be quite difficult to concentrate on how you are dialing the safe lock combination wheels while being distracted by your aching back, stretching to reach the dial while you struggle to maintain your view through the eyepiece of your scope.
You must have good references of how safes are constructed or experience in certain safe designs and construction to succesfully drill from the side. When faced with your next decision about attempting a safe opening by side drilling or top drilling, remember time spent in determining the design and construction of the safe you are opening may save you lost time in additional repairs due to poor decisions. Safe opening by side drilling will become your preffered method of safe opening in many more safe openings and should not be something that intimidates you. Side drilling or top drilling is often the most efficient and preffered method of safe opening.

Amsec KPL 2000 electronic digital safe combination lock
Changing from mechanical safe lock to electronic keypad safe lock
The digital or electronic combination lock has often replaced the mechanical combination lock in new safes as standard equipment. The digital combination lock eliminates the need to rotate the dial to align the wheels of a mechanical safe combination lock and removes any need to remember which direction to turn a dial type safe combination lock. While mechanical safe combination locks will undoubtedly continue to be used for many years to come, the Amsec KPL 2000 series offers features which make combination entry far easier for most users of safes. Changing from a mechanical safe lock to an electronic keypad offers convenience and flexibility of combinations available to the end user.
AMSEC introduced the KPL2000 series digital combination Lock in 1990. These locks have evolved over the years, adding more features as the electronics have become available. The KPL2000 series locks include three basic components. The lock, keypad assembly and electronics module. The KPL2000 electronic safe locks have a footprint similar to standard mechanical combination locks.
The AMSEC KPL2000 series digital combination locks are available in two basic configurations-the KPL2000 lock equipped with the standard bolt and the KPL2000S lock equipped with the slambolt. The KPL2000S slambolt is designed for wall safes and similar types of safes where there is no boltwork. To prevent bouncing or vibrating the bolt open on a locked safe, the KPL2000 series locks have a patented inertial counterweight mechanism.
The electronics module contains the functional circuitry for the digital combination locks. It is located inside the safe within a plastic case. An 8 conductor modular phone cable connects the keypad with the electronics module.
The two part keypad enclosure assembly is installed into the safe door using the existing safe dial ring screw holes. The keypad is an industrial controls-type overlay with stainless steel contacts. A red LED indicates operation of the keypad. The keypad enclosure is secured to the assembly using two 3/16" allen screws. Four AA batteries are used to power the KPL2000 and are located on the bracket assembly of the keypad enclosure assembly.
The following instructions describe a retrofit of the KPL2000S slambolt into an AMSEC WS1514 wall safe with an existing mechanical safe combination lock. The solid steel 3/16" thick door is mounted to the safe body with a continous non-removable hinge. The lock bolt acts as the locking mechanism and no additional boltwork is required in the door.
Replacing dial type, mechanical safe combination lock with an Amsec KPL 2000 S electronic keypad safe combination lock
Removing The Existing Mechanical Safe Lock, Dial and Ring
Step 1. Remove the back cover of the mechanical combination lock.
Step 2. Remove the spline key using a pair of pliers or side cutter.
Step 3. Unscrew the drive cam.
Step 4. Remove the dial and spindle.
Step 5. Unscrew the four Phillips screws securing the combination lock onto the door.
Step 6. Remove the dial ring.
NOTE: the sample WS 1514 wall safe has the dial ring attached to the safe door with double stick tape. There were no dial ring screw holes. Two #8 x 32 threads per inch tapped holes are required to install the KPL2000S digital lock. Do not drill through the door.
Installing The Amsec KPL 2000 S Electronic Keypad Safe Lock
The installation of the KPL2000S Digital Lock in a wall safe is pretty straight forward. There is no bolt work, insulation, or other components to interfere with this installation.
Step 1. Use a file to remove any burrs or sharp edges from inside the spindle hole.
Step 2. Loosen the two screws on the sides of the keypad enclosure using the 3/16" Allen wrench. Slide the keypad enclosure from the keypad bracket.
Step 4. Slide one end of the 8 conductor modular telephone plug connector through the spindle hole. If the plug will not slide through, the opening must be enlarged or the 8 conductor plug must be removed to feed the wire through the spindle hole. If the safe is equipped with hardplate and the spindle opening is too small for the plug to slide through, the modular phone plug must be cut from the end of the cable and a new modular connnector installed after passing the cable through the spindle hole. This type of connector is readily available at local electronics supply stores or larger, well stocked home improvement stores.
Step 5. Install the keypad bracket over the spindle and dial ring openings using the two 8-32 x 3/8" Phillips head screws.
Step 6. Insert the 8 conductor modular telephone plug through the spindle hole leaving enough cable on each side of the door to complete the installation. If one of the 8 conductor plugs was removed, install a new plug. There is a small rib on one side of the cable. Use this rib as a guide to position the plug.
Step 7. Slide the cable through the door without twisting or binding. Route the cable within the slotted groove in the lock body. Mount the lock onto the door using the four 1/4"-20 x 3/8" screws. Nylon washers are supplied for installation where the mounting plate is less than 1/4" thick.
Where applicable, re-attach any relock mechanisms built into the door.
Step 8. Attach the telephone cable plug into the socket in the electronics assembly.
Step 9. Mount the electronic assembly onto the safe door using double stick tape. NOTE: For the WS 1514 wall safe, locate the electronics assembly away from the shelves, as the door will not close.
Step 10. Connect the 8 conductor modular telephone plug and the power connector into the keypad bracket. Wrap any excess wire and slide the keypad enclosure onto the keypad bracket. Snug the two Allen screws.
Step 11. Test the operation of the KPL2000S with the door open.
Programmimg the Amsec KPL 2000 Electronic Safe Combination Lock
The KPL2000 series digital combination lock operates using the keypad as the input device. A six to eight digit combination is programmed. The "C" key provides two functions: It activates the circuitry and clears the system when an improper keystroke sequence is entered.
The factory set combination is C-1-2-3-4-5-6#. With the door open, test the operation four to six times to be certain the solenoid retracts and holds for 3 seconds.
To change the combination:
Step 1. With the safe door open, remove the rubber cap and depress the change button in the electronics module using the eraser end of a pencil. The red LED on the keypad cover will illuminate.
NOTE: Do not use the writing end of the pencil as the graphite tip may break off and cause electrical problems.
Step 2. Dial the six to eight digit combination beginning with the first digit and finish by depressing the "#" key.
Step 3. Record this new combination and test the operation of the lock at least three times with the safe door open.
To resist manipulation attempts to unlock the AMSEC electronic digital combination locks, the units are programmed with a timed lockout feature. Once four incorrect attempts have been entered, the electronics lock out any further attempts to enter a combination for fifteen minutes. During this time period, any keystroke restarts the fifteen minute time delay.

Safe Opening - Meilink Safe
Cam Punching Method
Essential skills that an experienced safe technician should have:
- Knowing how to dial open a lock when manipulation is possible and is likely to be the most efficient method of entry.
- Knowing how to properly diagnose a malfunctioning lock.
- Knowing how to pull dials and when to pull dials on locks that allow pulling of the dial without damage to the lock.
- Knowing how to drill for drop in of the fence.
- Knowing how to drill the fence off.
- Knowing how to transfer wheel gates.
- Knowing how to drill carbide-included hard plate or through previously drilled safes with an effective repair in place.
- Knowing how to and when to cam punch a Meilink fire safe.
Most safe service technicians can do most of the items listed above. In my own experience, the three skills I am less likely to see in less experienced safe techs are knowing when to manipulate, knowing how to transfer the wheel gates and knowing when to punch the cam.
Although I am referring in this article to Meilink safes, they were actually produced by Center Manufacturing and were sold to Meilink, Sears, and others.
