The following pdf files describe the installation procedure and how to reset the combination to a new code.

You will need the current working combination and the access key in order to change the code. Sorry, there are no bypass codes, or secrect codes to reset the lock when you do not know the combination.

If the default is not the same as the 9600 series cabinet lock then the manufacturer of the safe box as set a new default combination - try the safe box manufacturer for more information.

If you have a working combination, you must follow the exact sequence in the pdf instructions above. There is no click when inserting the tool - there is a slight click when you rotate it, but only if the lock is in the correct reset mode. If you do not have a working combination - you may need to contact a local locksmith to reset the lock, or send it in to the Mr. Lock service center for evaluation. You may also contact Kaba Simplex technical at 800-849-8324.

Please email/contact our sales department - let them know the spring part number you are working with - I am not aware of any spring that needs to be preloaded, but maybe a quarter turn.

I tried to change the combination and followed step by step but now it seems to be stuck in "zero combination"? I tried changing the combination again without step #3 (entering current combination) but it still keeps retracting every time I turn the handle.

If this is an old lock you may need a replacement combination chamber. Sounds like zero combination per the instructions, but couldn't diagnose without having the lock on the service bench. You can send it in for diagnosis or seek out a local Locksmith. You might email our customer service department for more insight.
