Lost every key to your car? What actually happens next

All keys lost doesn't mean a tow truck and a dealer bill. Here's how a mobile locksmith replaces every key at your vehicle.

The short answer

In most cases a mobile auto locksmith can cut and programme a brand-new key at your vehicle — no tow, no dealer booking. The exact method depends on your make, model and year, which is why the first thing we ask for is your registration.

Why the registration matters

Your registration tells us the exact key blank, blade profile, transponder chip and immobiliser system your car uses. Two cars of the same make can need completely different keys, so guessing wastes everyone's time.

With the registration we can also tell you whether programming runs through the diagnostic (OBD) port or needs a bench read of a module — and what that means for time and cost.

What the job looks like

First we gain damage-free entry to the vehicle. Then a new blade is cut to your locks, the transponder is programmed to the immobiliser, and any remote functions are paired.

Before we leave, we test the blade, the remote and a full start cycle with you, so you know everything works.

When the dealer genuinely is the answer

A small number of vehicles and key systems genuinely need dealer involvement. If yours is one of them, we'll tell you on the call rather than booking a job we can't complete.

FAQs

Common questions

How long does an all-keys-lost job take?

Many are completed in a single visit. The exact time depends on the vehicle's key system — we estimate it on the call.

Is it cheaper than the dealer?

Often, yes — and there's no tow or workshop booking. We quote clearly before any work.

Transit Custom Ignition Repair.

"I cannot recommend Alec enough. My transit custom lock was not turning. I did not know Alec at this point and called another locksmith. To cut a long story short the other locksmith attempted a repair and then gave up, leaving me with a van I could no longer use. I called Alec who came out next day; he repaired the damage done by the other locksmith and custom made a replacement ignition barrel so one key still does the doors and the new ignition. I couldn't be more pleased. Price was very fair too!"

Can work on most cars! Pricing is very reasonable! Fast reliable service!

"Absolutely spot on! After ringing about 15 different companies who said they couldn't help and one company even saying the series of my car doesn't exist I found smarttech who I contacted who could finally help! The next day he came out and I now have access and a new key to my car! Fast and efficient polite service! Highly recommend!!"
