Rekeying changes the pins inside a lock so the old keys stop working and a new key takes over. The handle, deadbolt and finish stay exactly as they are. It is the quickest and least expensive way to take back control of who can get into your home or business, and it is what we recommend after a move, a lost key, a breakup or an employee leaving.
Prime Locksmith Services rekeys Schlage, Kwikset, Yale, Baldwin and most other brands on site in the St. Louis area. While we are there we can key every door to one key, set up a master key system, or upgrade the locks that need more than new pins.
For lock rekeying in St. Louis or any job for a residential locksmith in St. Louis, call (314) 745-4590.
Done at your door, usually lock by lock in a single visit.
Tell us how many doors, and whether you want one key for all of them.
Rekeying is priced per cylinder, so the quote is simple and upfront.
We take the cylinder out of each lock without removing the whole lockset.
Old pins out, new pins in, matched to a freshly cut key.
Every lock is tested with the new keys before we leave.
If your locks work well and you like how they look, rekey them. If they are worn, damaged, low quality or you want a stronger deadbolt or a keypad, replace them. See lock installation for upgrades.

What moves the price: the number of cylinders, the brand and keyway, whether all locks are keyed alike or to a master key system, and the hardware you choose for any upgrades.
You have no idea who still holds a key from the last owner, the builder or the realtor.
Lost keys, a former roommate, or a tenant who left. Rekey and the old keys are useless.
We key the front, back and garage doors alike so one key opens them all.
For landlords and businesses: each door has its own key, and a master opens them all.
Pick-resistant cylinders with keys that can’t be copied at a hardware store.
Longer screws and reinforced strikes help a door resist being kicked in.
