The final price depends on the door more than the lock: an old mortise pocket, a warped slab or a hurricane impact door adds labor. We quote before we start, and the quote is the price.

Do You Need a Locksmith to Change Locks?

Not always. Swapping a standard deadbolt into the same holes is a reasonable DIY job. Call a locksmith when the new lock does not line up with the old holes, when the door is an impact door or has a mortise lock, when you want every door on one key, or when the lock was damaged in a break-in. A locksmith also brings the right strike plate and screws, which decide how well the lock holds against a kick. Doing it yourself? Our step-by-step lock replacement guide walks you through it.

When Should You Change Your Locks Instead of Rekeying?

Change the lock when the hardware itself is the problem; rekey it when only the keys are. Replace the lock when it was damaged in a break-in, when the key sticks or the bolt does not fully throw, when it is a cheap builder-grade lock you want to upgrade, or when you want a smart lock or a high-security lock. If the lock works well and you only need old keys to stop working, rekeying costs less.

Changing Locks After a Break-In

Change the damaged lock the same day, and check the frame before you trust the new one. After a forced entry the strike plate, the jamb and sometimes the door edge are cracked, and a new lock in a broken frame will fail the same way. We replace the lock, reinforce the strike with three-inch screws into the stud, and give you an itemized receipt with our license number for the insurance claim.

Lock Changes for Landlords and New Homeowners

Every new owner should assume that previous owners, agents and contractors still hold keys. For a quick, low-cost fix, rekey; for a full upgrade, replace the locks and key the whole house to one key. Landlords with frequent turnover save over time with registered keys that tenants cannot copy, such as Mul-T-Lock.

Lock Change in West Palm Beach and Palm Beach County

We change locks across West Palm Beach, including El Cid, Northwood, Flamingo Park and the downtown condos, and across Palm Beach County from Boca Raton to Jupiter. Many older West Palm Beach homes still have original hardware from the 1950s and 1960s, so we bring replacement deadbolts that fit older door preps without new drilling. Palm Beach County: (561) 570-4070.

Typical Situations We Handle

New homeowners in Northwood, West Palm Beach

A couple buys a 1950s house with four exterior doors and four different keys. We replace the front and back deadbolts, rekey the side and garage doors, and key all four to one key — about an hour of work, with the hardware matched to the older door preps.

Hollywood rental after a break-in

A tenant reports a kicked-in back door. We replace the damaged deadbolt, reinforce the strike plate with three-inch screws into the stud, and rekey the front door so the old keys stop working. The owner gets an itemized receipt for the insurance claim the same day.

Lock Change Questions

How much does it cost to change all the locks on a house in South Florida?

Most homes have three exterior doors. Replacing all three with new standard deadbolts keyed to one key typically costs $225–$450, plus a $29 service call. If some locks are in good shape, rekeying those instead lowers the total.

Can you install a lock I bought myself?

Yes. Installing a lock you supply starts at $65 for labor. We check that it fits your door before we start; if the new lock needs different holes or a different backset, we tell you the extra cost up front.

Can you change the locks the same day I call?

Usually, yes. Our technicians carry standard deadbolts, knobs and levers in common finishes, so most lock changes are done on the first visit. A standard lock takes 15–30 minutes.

Do you need to see proof of ownership before changing a lock?

Yes. We ask for ID that matches the address, or a lease or closing documents. It protects you: no one should be able to have your locks changed without showing they live there.

Should I change the locks myself or hire a locksmith after a break-in?

Hire a locksmith. After a forced entry the frame and strike plate are usually damaged too, and a new lock in a cracked frame fails the same way. We repair the strike, replace the lock and give you a receipt for your insurer.
