We have several other series of locks that we have used throughout our history.
If you do not see your lock number listed above, you can call us at 937-228-1662 to see if we still have keys available.
A50M Series Chest Keys:
A50M keys are copies of original keys that we still have at our factory. Each key that we have copied by our locksmith is tested in a sample lock at Gerstner & Sons to ensure it works the lock correctly before we ship it to you.
If the key you received does not operate your lock, we have been told by customers that you can try to shorten the length of the key, or the height of the key to try and make it fit in your lock (see picture below).
If this does not work, the only suggestions we have are to take the key and lock to your local locksmith to see if they can get it to work, or to replace the lock on your chest.
If you need to replace the lock on your chest, you can exchange the key toward the purchase of a lock, without a restocking fee on the key. Keys returned for a refund only have a 10% restocking fee.
