Huwil Locks (


There are no refunds or returns on office furniture keys, this keeps our prices low

If your key goes into the lock but did not work please check the following:

Did you order the correct key, the numbers stamped on the lock can be hard to read, use a magnifying glass or take a picture with your cell phone and zoom in.

Sometimes the number on the lock is wrong or the lock has been rekeyed, you will require onsite service to repair or a new lock is required

If the key goes in and turns but the furniture does not lock then there is a problem with the locking mechanism

If the key won't go in check and see if there is a broken key inside the lock, if so it will have to be removed or you will need a new lock
