Frequently Asked Questions for Belsize Park Drivers

Can you make a new car key without the original in NW3?

Yes. We can create a key from your vehicle using key code data or by decoding the lock. We then program the transponder or smart key to your immobiliser. This is often quicker and more convenient than going to a dealer and avoids towing.

Will you damage my car to unlock it?

Our approach is non-destructive wherever possible. We use specialist tools to pick or decode locks. In the rare event that a component is already damaged or a particular model requires drilling, we’ll explain options and costs before any work.

How long does it take to get a new car key?

Most replacements can be completed the same visit once we’re on-site, subject to vehicle make/model and key type. Smart/proximity keys can take longer due to security pairing, but our dealer-level equipment streamlines the process.

My car says “key not detected” — what should I do?

Try a fresh battery in the fob and hold the key near the emergency start area (see your manual). If that fails, call us. We’ll test the fob, check immobiliser sync, and perform reprogramming if needed. See key fob not working for more guidance.

Do you cover vans and commercial vehicles in Belsize Park?

Yes. We support vans and fleets, including Ford Transit, Mercedes Sprinter, VW Transporter, and more. We can replace, cut, and program keys and handle lock or ignition issues to keep your workday moving.

Are your technicians insured and DBS-checked?

Absolutely. We carry public liability insurance and all technicians are DBS-checked. We also provide warranties on keys and workmanship where applicable.

How much does car key programming cost in North West London?

Prices vary by brand, model, and key type. We don’t publish fixed prices because each job is different. For an accurate figure, please request a quick quote. You can also read more on auto locksmith prices in North West London.
