Yes, it is possible to order additional keys, please visit the ”Key Ordering” section of our website and make sure to have your control card or tag handy.

First off, we recommend to lubricate your lock mechanism and around the cylinder with a lubricant without silicone base, we use PL-100 by Prolab. A monthly lubrication with this type of lubricant is highly recommended. Note that WD-40 is not recommended because it is sticky and it could jam the lock mechanism of your AMP Lock. 

Also, depending on the climate, we recommend to presoak your AMP Lock in anti-freeze like ”Prestone” for one full night twice a year. If it is cold or if it snows in your area, we recommend doing it at beginning of the fall and if possible in January. Make sure you unlock your AMP Lock and let all the components open. After this treatment, lubricate your lock mechanism and around the cylinder with PL-100 or any lubricant without silicone base.

At first, please check that REAL is written on your key, so you are sure to have the right key to open your Amplock lock. Secondly, you have to check how far the the key has turned in the cylinder lock. To unlock your AMP Lock, the key has to turn ¾ of a rotation. Here are different situations and how you could potentially resolve them:

  1. The key is turning ¼ of rotation in the cylinder lock: verify your key, has it been damaged? Is it the right key for this AMP Lock? Try a new key if possible or order a new one on our website (
  2. The key is turning between ¼ and ¾ of rotation in the cylinder lock: lubricate your lock with a lubricant without silicone base (we are using PL-100 by Prolab) and add compressed air in the cylinder lock to remove all grime. After few cleaning operations, your key should turn in order to reach ¾ of rotation, which is where it should be.
  3. The key is turning more than ¾ of rotation or at 360° (1 complete rotation): contact AMP Lock or any locksmith because your cylinder lock has been damaged and the internal mechanism has been broken.
  4. The key is turning ¾ of rotation, but the lock doesn’t open : your cylinder lock is unlocked so something has stopped the cylinder from opening. We recommend to clean around the cylinder with a lubricant without silicone base such as the PL-100 by Prolab and to add compressed air to remove grime. After these operations, try to open the lock again. If it’s still not working, please contact AMP Lock.

If you registered your lock on or if you already ordered additional keys/lock with us, your key code is registered, so contact us and we will be able to help you. Note that if you still have 1 key, we will be able to help you also, please contact us with your key number and photos of your key.

If you didn’t registered your lock and/or didn’t ordered additional keys/lock with us and/or didn’t have a key, you will have to make the cylinder lock destroy by a locksmith.
