Lock Rekeying in St. Louis, MO

New Keys Without New Locks

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.

How Rekeying Works

Done at your door, usually lock by lock in a single visit.

Count your locks

Tell us how many doors, and whether you want one key for all of them.

Get the price

Rekeying is priced per cylinder, so the quote is simple and upfront.

Remove the cylinder

We take the cylinder out of each lock without removing the whole lockset.

Repin to a new key

Old pins out, new pins in, matched to a freshly cut key.

Test and hand over keys

Every lock is tested with the new keys before we leave.

Rekey or replace? A quick rule.

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.

Rekeying and Upgrade Prices

Prime Locksmith Services’ own price ranges from our pricing page. Rekeying is priced per lock cylinder.

ServiceTypical price

Commercial re-key (per cylinder)$75 to $300
Residential lock change, installed$75 to $250
Commercial lock change (per cylinder)$150 to $600

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.

When to Rekey, and What We Upgrade

You just moved in

You have no idea who still holds a key from the last owner, the builder or the realtor.

A key went missing

Lost keys, a former roommate, or a tenant who left. Rekey and the old keys are useless.

One key for every door

We key the front, back and garage doors alike so one key opens them all.

Master key systems

For landlords and businesses: each door has its own key, and a master opens them all.

High-security cylinders

Pick-resistant cylinders with keys that can’t be copied at a hardware store.

Stronger deadbolts and strike plates

Longer screws and reinforced strikes help a door resist being kicked in.
