The Service Most Drivers Don't Know Exists

Rekey vs. Replace —
Why You Usually Don't Need New Locks

When old keys need to stop working, most drivers assume the locks must be replaced. Usually they don't. Here's the difference — and why rekeying is the smarter first option.

Usually the Right Answer
Rekeying
Inside every lock cylinder is a set of small wafers matched to your key's cuts. Rekeying swaps those wafers to match a new key cut — the hardware stays, but the lock now answers to a different key.
Old keys stop working instantly — every copy out there becomes scrap metal
Your existing hardware stays — nothing thrown away, nothing installed
Faster and less expensive than replacement
All cylinders keyed alike — one key for doors, trunk, and ignition
Only When Actually Needed
Replacement
A brand-new cylinder is installed. Necessary when the lock itself is physically damaged — worn beyond repair, seized, drilled in a break-in attempt, or glued shut by a DIY extraction attempt.
Right after break-in damage, severe wear, or a glued cylinder
New cylinder comes with its own key — we rekey it to your existing key so you're not carrying two
We diagnose honestly on-site: if a rekey does the job, we don't sell you a replacement — ignition repair & replacement covers the damaged-cylinder cases

When Rekeying Is the Move

The Four Moments
Smart Owners Rekey

Rekeying isn't a repair — it's a security decision. These are the four situations where it's exactly the right one.

Situation 1 — Security
Your Keys Were Stolen
Programming new keys erases the stolen key from the immobilizer — it can't start the engine anymore. But here's what most people miss: the metal blade can still physically open your doors until the locks are rekeyed. If the thief may know where you live or park — keys taken with a wallet, bag, or from your home — rekey the doors and the stolen key becomes completely useless. We do both steps in one visit; see also lost & stolen car keys.
Situation 2 — Peace of Mind
You Just Bought a Used Car
How many copies of your key exist right now? You have no idea — and that's the problem. Previous owners, their family, valet copies, keys made during old repairs. Rekeying makes every unknown copy worthless and makes you the only keyholder from day one. It's the security step almost nobody takes, done in your driveway in about an hour.
Situation 3 — After a Repair
A Cylinder Was Replaced — Now You Have Two Keys
A replacement ignition cylinder or door cylinder comes with its own new keys — leaving you with one key for the ignition and another for the doors. We rekey the new cylinder to match your existing key, so one key runs the whole car again. If another shop left you in the two-key situation, we fix it in one visit.
Situation 4 — The Mystery Mismatch
Door Key and Ignition Key Are Different
Common on used cars with a repair history: somewhere along the line a cylinder was swapped without being rekeyed, and now the car needs two keys to function. We re-pin the cylinders back to a single key cut — one key in your pocket, everything works, the way the factory intended.

FAQ

Cylinder & Ignition Rekey —
Most Asked Questions

The questions DC and Maryland drivers ask most about rekeying.

What's the difference between rekeying and replacing locks?

Rekeying keeps your hardware and changes the key; replacement swaps the hardware. We re-pin the internal wafers so the lock accepts a new key cut — old keys stop working instantly. It's faster and cheaper than replacement and achieves the same security goal. Replacement is only needed when the lock itself is physically damaged. Call (202) 993-9919.

Should I rekey after my keys were stolen?

Yes — new key programming alone isn't enough. Erasing the stolen key from the immobilizer stops it from starting the engine, but the metal blade can still open your doors until the locks are rekeyed. If the thief may know where you park, rekey the doors and the stolen key becomes completely useless. We do both in one visit — see lost & stolen car keys. Call (202) 993-9919.

Should I rekey when I buy a used car?

It's the smartest security step almost nobody takes. You have no idea how many key copies exist — previous owners, family members, valets, old repair shops. Rekeying kills every unknown copy and makes you the only keyholder. Done in your driveway in about an hour. Call (202) 993-9919.

Can you rekey a new ignition cylinder to my existing key?

Yes — this is one of the best uses of rekeying. A replacement cylinder normally arrives with its own keys, leaving you carrying two. We rekey it to match your existing key so one key keeps running the doors, trunk, and ignition. If a past repair left you in the two-key situation, we fix that too. See ignition repair & replacement. Call (202) 993-9919.

My door and ignition use different keys — can you fix it?

Yes. Mismatched locks usually mean a cylinder was replaced somewhere along the line without being rekeyed. We re-pin the cylinders back to a single key cut so one key operates the entire vehicle again — the way it left the factory. Call (202) 993-9919.

How long does a car rekey take?

Most rekey jobs take 30–90 minutes on-site depending on how many cylinders are involved — a single door is fastest; doors, trunk, and ignition keyed alike takes longer. Includes cutting the new key and testing every lock. Available 7 days a week including Sundays across DC and Maryland. Call (202) 993-9919.
