Change Your Own Door Lock

CHANGE-A-LOCK®  A Division of Topper Hardware, Inc. has been in business since 1978. We currently offer 10 different do-it-yourself rekeying kits that can be used with a total of 18 different major manufacturer type locks. Each rekey kit is $12.95 and will rekey 6 single cylinder locks. Each lock you put a key in is a single cylinder so if you have a deadbolt keyed on both sides, that would count as 2 single cylinder locks.

Our rekey kit comes with 2 pre-cut keys, detailed instructions and all the special tools needed except for a common screwdriver. Manufacturing our rekey kit we  use hundreds & hundreds of key cut combinations to insure privacy.

Old key is needed for most locks in order to take out the lock cylinder plug then new key is used to rekey lock. 

Customers with more than 6 single cylinder locks may, at time of ordering, add additional pin sets and/or precut keys which will match the kit ordered.

Note: You must use the keys provided in rekey kit for rekeying. Pins match keys in kit and are not to be used to rekey with any other keys!

If you order 2 or more rekey kits and wish to have them keyed the same please email us at immediately after placing your order. We can not match manufacturer's original key code with pins or keys.

NOTE: BALDWIN®, EMTEK®, & PEGASUS® LOCKS must have the Schlage KEY compatible cylinder AND YALE LOCKS must have the KWIKSET KEY compatible cylinder for rekey kit to work!

NOTE: If you have a WEISER "ELEMENT" LOCK you can order the KWIKSET 5 pin rekey kit for the ELEMENT takes apart the same as the KWIKSET LOCK.


Schlage®, Baldwin®, Emtek®, & Pegasus®   5-pin cylinder locks may come with a 6-pin key cylinder. The 6-pin key cylinder only has bottom pins in the first 5-pin holes, with the 6th. pin hole position being empty.


When you insert the key from the CHANGE-A-LOCK® rekey kit into the 6-pin key cylinder, and using the special instructional sheet to replace the bottom pins, the last hole after the tip of the key is the 6th. pin hole position.

Therefore, the 6th. pin hole position is not used when rekeying.
