3-in-1 by Mul-T-Lock
The cylinder is built to allow a change of combinations by the insertion and operation of the next key in a sequence of 3 keys. Introduction of each new key invalidates the previous key combination. When all 3 combinations have been used, the cylinder may be reset by a Spadina Security Locksmith. The product is available with the 3 keys colour coded or the keys can be made when required by the user.
First you use the green set of keys. Whenever the combination needs to be changed (rekey) simply start using the yellow key. The green key will automatically be cancelled. Once again you may change the combination by applying the same process with the red key. The yellow key, as well as the green, will be automatically locked out.
