Variable Combination Cylinder 3-in-1 (Change Lock Combination by Yourself)
 

This cylinder is built to allow a change of combination by the insertion and operation of the next key by a sequence of 3 keys. Introduction of each new key invalidates the previous key combination. The product is packaged with the 3 key types, colour-coded (GREEN, YELLOW & RED) and clearly marked in a sequence, to guide the customer in a correct usage. The next time you change tenants/maid or lost your key, this MULT-T-LOCK Variable Combination 3-in-1 product enables you to change lock combinations at your finger tip….
