Not every lock problem needs a new lock. If your lock still works fine and you just want to make sure old keys stop working, rekeying is usually all you need. It costs less than replacing hardware, and you walk away with new keys that only you have. If we think you need new hardware, we will tell you. If you don’t, we won’t sell it to you.

Before you pay the dealership hundreds for a car key…call us. 🚗🔑

Modern car keys aren't always as simple as cutting a piece of metal.

Depending on your vehicle, you may need a transponder chip, remote, or key fob programmed to the vehicle.

That doesn't mean the dealership is your only option.

Big D Lock & Key works with a wide range of automotive keys, remotes, and fobs—and we're often able to save you money.

It never hurts to ask us first.

Worst case? You get an honest answer.

Best case? You just saved yourself a bunch of money. 💰

Just moved into a new house? Change the locks. 🔐

Not because your new locks are necessarily bad.

Because you have no idea who still has a copy of the old key.

Previous owners. Family members. Contractors. Babysitters. Dog walkers. That neighbor who “had a spare.”

You don't need to replace every lock, either. In many cases, we can rekey your existing locks so the old keys no longer work.

Same locks. New keys. Much less hassle.

And yes, usually less expensive than replacing everything.

That’s the kind of locksmith advice we like giving. 😉

Before you replace the lock, ask a locksmith. 🔑

Having trouble with a lock doesn’t automatically mean you need a brand-new one.

Sometimes it just needs a repair. Sometimes it needs to be rekeyed. And sometimes there’s a simple issue that can be fixed without replacing the whole thing.

Don’t spend $200 when you only need a $20 fix.

If you’re not sure what’s wrong, bring it to Big D Lock & Key and let us take a look and answer any questions.

We’ll tell you what you actually need. No BS.

If you recently purchased new locks from the local hardware store, only to find out that the locks don’t fit in the old holes; there is a good chance that your original doors may not be prepped correctly to fit modern hardware.

If this is not a job you are up for, we would be happy to help and re-drill your door to accommodate your new locks (with no extra holes or tacky cover plates).
