How Much Does It Cost to Rekey a Lock?

Rekeying is one of the most affordable ways to secure a home or business after a move, a lost key or a tenant change. Instead of replacing the lock, you change the pins inside the cylinder so a new key works and the old key no longer does.

Average Cost to Rekey a Lock

The cost to have a lock rekeyed typically ranges from about $15 to $50 per lock, depending on the type of lock and your location. If you hire a locksmith to come to you, there is often a service call fee as well, commonly around $50 to $100. These are general ranges — always ask your locksmith for a quote before work begins.

What Affects the Price?

• Lock type: standard residential pin-tumbler locks are the least expensive; high-security, commercial or specialty cylinders cost more.
• Number of locks: rekeying several locks to the same key at one visit usually lowers the per-lock cost.
• Service call and timing: mobile visits, after-hours and emergency calls add to the total.
• Master keying: setting up a master key system takes more planning and pins than a simple rekey.

Rekeying vs Replacing Locks

Rekeying keeps your existing hardware and only changes the pins, so it is usually much cheaper than buying new locksets. Replacement makes sense when the lock is damaged, worn out, or you want to upgrade security or style.

DIY Rekeying with a Kit

If you rekey often — landlords, property managers, maintenance staff or new locksmiths — a rekeying kit can pay for itself quickly. Brand-specific kits such as the Kwikset re-keying kit or the Schlage rekeying pin kit include color-coded pins and the tools you need. Beginners can start with the DIY Professional Lock Rekeying Starter Kit.

How Long Does Rekeying Take?

An experienced locksmith can rekey a standard residential cylinder in a few minutes once it is removed from the door. DIY rekeying takes longer the first few times as you learn to read keys and match pins.
