Mobile auto locksmith cutting and programming a replacement key after a customer lost their car keys

Professional. Mobile. Trusted.

Losing car keys is the job we get called out for most, and the one people most often overpay for. The instinct is to ring the dealer, who will usually ask you to have the car recovered to them and wait days for a key to arrive. We do the same work at your vehicle: read the security data, cut a new blade to the original code, program the key to the immobiliser, and where the platform allows it delete the missing key so nobody can use it. Tell us the registration and we will tell you exactly what your car needs and what it costs before anyone sets off.

  • All keys lost — no spare needed, key generated from the vehicle's own data
  • Missing keys deleted from the immobiliser where the platform supports it
  • Cut and programmed at your car — home, work, airport car park or roadside
  • BMW CAS/FEM/BDC, Mercedes FBS3, VAG MQB/MQB48, Ford HU101 and more
  • Cars, vans and fleet — Transit, Transporter, Sprinter, Vivaro, Crafter
  • From £180 — fixed quote against your registration before any work starts
  • 12-month parts and labour warranty, fully insured
  • Most jobs finished in 60–120 minutes on site

Which lost key situation are you in?

The price and the time on site depend almost entirely on this. Tell us which one describes you and the quote is fixed from there.

Lost the only key you had

All keys lost. No spare, no way in, nothing to clone from. We cut a new key from the vehicle's own data, program it to the immobiliser and — where the platform supports it — delete the missing key so it can no longer start the car.

Lost one key, still have a spare

Much cheaper and much quicker. Bring us the working key and we cut and code a replacement on the driveway, usually inside the hour.

Keys lost away from home

Airport car park, station, hotel, gym, beach, festival. We come to the vehicle — you do not need to arrange recovery.

Keys stolen

Priority is deleting the missing keys from the immobiliser so they no longer work, then supplying replacements. Ask us about the order to do things in if the car has already been targeted.

Key lost from a van or fleet vehicle

Transit, Transporter, Sprinter, Vivaro, Crafter, Caddy and the rest. We attend depots and yards and can do multiple vehicles in one visit.

You are not sure they are lost

If a key stopped working rather than went missing, it may be a dead battery, a damaged blade or a fault rather than a lost key. Say so when you call — it is a far cheaper job.

Common Lost-Key Scenarios

What happened to your keys?

Every lost-key situation is slightly different. Here are the four we handle every week across West London, Heathrow, Staines, Slough and Reading — with realistic on-site timings.

All Keys Lost (No Spare)

Most stressful — and most expensive at the dealer (£600–£1,400 + recovery). We attend on-site, read the immobiliser, generate a brand-new master key and program it to your car. No tow, no main-dealer wait. Typical on-site time: 60–120 minutes.

Spare Key Needed

Still have one working key? We cut a precision blade copy, clone or learn the transponder and program a fully working spare. From £180 for most vehicles. Booked in advance or same-day across TW, SL, UB, HA, RG postcodes.

Stolen or Suspected Theft

Keys stolen with the car nearby? We can disable the lost key from the car's memory so it can no longer start the vehicle, then issue you a new authorised key. Police report number helps but is not always required.

Key Snapped in Lock or Ignition

Broken-blade extraction, then a fresh cut and re-program in the same visit. We carry blank blades for VAG HU66, Ford HU101, BMW HU92, Mercedes HU64 and most Asian profiles.

By Vehicle Make

Lost car key pricing by make

Indicative on-site prices for spare keys vs all-keys-lost. Final quote depends on year, model and key type (blade, flip, smart proximity). We confirm the price before we start — no surprises.

BMW

From £320 (spare) · £480–£780 (all keys lost)

CAS1/2/3/3+ via OBD, CAS4/4+ via bench (typically 1 Series, 3 Series F30, 5 Series F10, X1, X3, X5). FEM/BDC F-series and G-series handled with proper ISN read — no soldering risk to your module.

Frequently Asked Questions

I have lost my car keys — what do I do first?+

Check the obvious places, then call us with the registration, make and model. We will tell you on the phone whether you need a full all-keys-lost job or a cheaper straightforward replacement, roughly how long it takes, and a fixed price before anyone travels. Do not book a recovery truck to the dealer before speaking to us — that is usually the most expensive route available.

Can you replace lost car keys if I have no spare at all?+

Yes, on the vast majority of vehicles. This is called an all-keys-lost job: we read the vehicle's own security data, cut a new blade to the original code, and program a brand-new key to the immobiliser at the roadside. A handful of the newest and most security-gated models genuinely are dealer-only — we check your registration and tell you honestly up front rather than attending and failing.

How much does lost car key replacement cost?+

Lost car key replacement starts from £180. The final price depends on the make, model, year and key type — a basic transponder key is a very different job to an all-keys-lost proximity key on a modern German car. You get a fixed quote before any work begins,.

How long does it take?+

Most jobs are finished in 60–120 minutes on site. All-keys-lost and security-gated vehicles can take longer, and we tell you which yours is before booking rather than after.

Will the lost key still work if someone finds it?+

On most platforms we can delete the missing key from the immobiliser as part of the job, so it will no longer start the vehicle. Ask for this explicitly if the keys were stolen rather than mislaid — it is the single most important part of the job.

Do I need to get the car towed to a dealer?+

Almost never. We are fully mobile and carry key-cutting and programming equipment to your vehicle, wherever it is parked.

Which areas do you cover?+

West London, Heathrow and all terminals, Staines, Slough, Windsor, Hounslow, Uxbridge, Richmond, Twickenham, Reading, Woking, Bracknell, Maidenhead and the surrounding Home Counties.
