Rekey or Replace: What to Do With the Locks After You Buy a Home in Gilbert

You get the keys at closing, and it feels like the house is finally yours. It mostly is. What nobody tells you is that you have no idea how many copies of the old keys are out there. The previous owners had a few. So might a relative who watered the plants, a neighbor with a spare, a contractor, a cleaner, a listing agent. None of those people did anything wrong, but none of them are yours to trust either. Changing the locks is the quickest way to close that question, and you can do it before you unpack a single box.

Rekey and replace are not the same job

Rekeying changes the inside of the lock so the old keys stop working and a new key works instead. The locksmith takes the cylinder apart, swaps the small pins that match the cuts on the key, and puts it back together. The hardware on your door stays where it is: same deadbolt, same handle, same look. Replacing means taking the whole lock off the door and installing a new one with new keys cut for it.

For most homes in Gilbert the hardware is perfectly fine and only the keys are the problem. A rekey does exactly what you need in that case, and it usually takes less time than a full swap. Replacing makes sense when a lock is worn out, loose, damaged, or just a style you can't stand. It also makes sense if the builder put the cheapest deadbolt available on your front door and you'd like something sturdier.

One key for every door, or a different key for each

This is the decision people don't expect to make. When a house is rekeyed, every lock can be set to the same key, so one key on your ring opens the front door, the back door and the garage entry. That's convenient, and it's what most households choose. The other option is a unique key for each door, which lets you hand someone a key that opens one door and nothing else.

Think about who actually needs access. If it's only your household, one key is simpler and you'll stop carrying a ring of five. If you rent out a room, run a home office, or have a standing cleaner or pool service, separate keys let you control who reaches which door. You can also mix the two: one key for the front door and the garage entry, a second key for the back door and the side gate. Tell the locksmith how you actually live and they'll set it up that way. Locksmith Of Gilbert will cut as many keys and change as many locks as you need, so there's no reason to settle for a layout that doesn't fit your house.

Will a home warranty pay for it?

Check this before you spend anything. In many cases a home warranty will cover the cost of a rekey after you buy a home. Not every plan does, and the terms vary from one warranty company to the next, so read your paperwork or call them and ask before the visit. If it's covered, you may only need to confirm the work with the locksmith and keep a record of it. If it isn't covered, you've lost nothing by asking.

It's also worth finding out whether the seller or your agent included a warranty as part of the sale. Some buyers have one and don't realize it until the first thing breaks. A rekey is a good first claim to try, since it's a small job with a clear purpose.

What a mobile visit looks like

Locksmith Of Gilbert is a mobile locksmith, so nobody has to carry a lock to a shop. The locksmith comes to the house with the tools and key blanks, works through each door, and finishes by trying every new key in every lock and showing you that the old key no longer turns. That last step is how you know the job is actually done, so ask for it whoever you hire.

Plan to be home so you can point out every lock. Walk the property first and count them: the front door, the back slider or patio door, the door from the garage into the house, any gate with a keyed padlock, and the locks on a shed or casita. The ones people forget are the garage entry and the side gate, and they're often the easiest way into a house.

When replacing is the better call

Rekey when the hardware is sound. Replace when a deadbolt sticks or grinds, when the strike plate is screwed into a cracked frame, when a handle wobbles, or when you want something better than what came with the house. A new lock is also the right move if you're adding a smart lock or want a higher-security deadbolt on the front door. A locksmith can tell in a few seconds which situation you're in, and it costs nothing to ask them to look.

Whichever way you go, do it soon after closing. Every week you wait is a week that unknown keys still work.
