Key Types We Replace
- Basic cut keys — older vehicles (pre-1995) with no chip. Cut from code or by decoding the barrel. Fastest job.
- Transponder keys — chip in the key head programmed to your factory immobiliser. Standard from mid-1990s. Cut and programmed in one visit.
- Remote / flip keys — combined blade and remote fob. Common from 2005 onwards. Requires both blade cutting and remote programming.
- Smart / proximity keys — keyless entry and push-button start on premium and newer vehicles. Full diagnostic programming on-site.

Frequently Asked Questions
Can you replace a car key without the original?
Yes. Using your vehicle's VIN and professional diagnostic equipment, we cut and programme a new key even when all originals are lost. This is one of our most common jobs. We authenticate directly with your vehicle's factory immobiliser — no original key needed.
How long does car key replacement take?
Most replacements take 30–60 minutes on-site. Basic cut keys take 15–20 minutes. Transponder programming adds 20–30 minutes. Smart key and proximity fob programming can take 45–90 minutes. We always complete the job in a single visit.
How much does car key replacement cost in London?
Prices start from £120 + VAT for a standard cut and programmed key. Premium key fobs (BMW, Mercedes, Audi) typically cost £180–£350 + VAT. All prices are fixed — quoted before we start, no hidden charges.
Is a mobile locksmith as good as a main dealer for key replacement?
Yes. We use the same professional diagnostic and programming equipment as main dealers. The key differences are speed and cost — we come to you the same day rather than requiring a dealer appointment weeks away, and we charge significantly less.
Do you cover all car makes and models?
Yes. We replace keys for all makes including Mercedes, BMW, Audi, VW, Ford, Vauxhall, Toyota, Nissan, Renault, Hyundai, Kia, Land Rover, Volvo and every other manufacturer. We carry blanks and programming equipment for all common vehicles.
Do I need to tow my car anywhere?
No. Our service is fully mobile. We come to your home, workplace, or roadside — wherever your car is located. No recovery needed. We carry everything required to complete the job at your location.
