Car Keys Stolen? The Steps That Actually Protect You

4 min read By Mobile Auto Locksmith Hamilton

Losing keys is inconvenient. Having them stolen is a security problem, because somebody knows what your car is. Here is the order to do things in.

A stolen key is a different situation from a lost one, and the difference matters. Somebody now has a working key and, if your address was in a wallet or a bag taken at the same time, they may know exactly which vehicle it opens and where it sits at night.

Move the car

Even just around the corner or into a garage. That single step removes the easy opportunity while everything else is sorted out.

If it cannot be moved, a steering wheel lock fitted tonight is a reasonable stopgap — the case for one is in are steering wheel locks worth it.

Report it

Report it to the Police and get a reference number. Your insurer will ask for it, and if the vehicle is used later it establishes when you lost control of the key.

Do this even if the key seems minor next to whatever else was taken. The reference number is what makes the rest straightforward.

Delete the old keys — the step people miss

A new key on its own does not stop the stolen one working. Both will start the car. This is the single most misunderstood part of the whole situation.

Deletion erases the old key codes from the vehicle so the stolen key becomes a piece of metal. On most modern makes we can do this at the same visit as cutting the replacement, and it is covered on our lost car keys page.

If house keys went too

Treat the house as compromised, particularly if anything with your address was taken at the same time.

Re-keying the existing locks is usually cheaper than replacing them, and our residential locksmith service handles that. If several doors currently take different keys, it is a sensible moment to have them keyed alike.

Afterwards

Once the immediate problem is dealt with, have two keys rather than one. Going back to a single key leaves you one incident away from the same position.

Getting it done quickly here

Key deletion is the urgent part, and we can usually attend the same day across Hamilton and the nearer Waikato towns.

If the vehicle is parked somewhere the thief knows, say so when you ring — that moves the job up the list.

Call us with the registration and we will confirm on the phone whether your vehicle supports key deletion, before you spend anything.

Common questions

Does a new key stop the stolen one working?

No. Both keys will start the car until the old ones are erased from the immobiliser. Deleting them is the step that actually protects the vehicle.

Can every car have old keys deleted?

Most modern vehicles can. A few older models with basic immobilisers cannot, and in those cases we discuss the alternatives. We confirm on the phone from your registration.

Should I tell my insurer?

Yes, and get a Police reference number first. Insurers generally expect both, and it protects you if the vehicle is used before you replace the keys.

Can you come out the same day?

Yes. Stolen keys are treated as urgent because the risk is live. Tell us when you call and we will prioritise it.
