Why London Drivers Choose William
Most auto locksmiths in London are call centres. You phone one number, and a different person turns up every time - often a subcontractor with limited training and generic equipment. William Bullard works differently. When you call Bullard Locks, William answers the phone, drives to your vehicle, and does the work himself. One person, start to finish.
William carries dealer-level diagnostic and programming equipment in his fully stocked mobile unit. That means transponder keys, proximity fobs, and remote keys are cut and programmed on-site - no towing to a dealer, no waiting days for parts. He covers all major makes including Ford, Vauxhall, BMW, Mercedes, Audi, VW, Toyota, and many more.
With over 30 years in the trade and a Metropolitan Police approved status, William is the auto locksmith North London trusts for car key emergencies, spare keys, and lockouts. No call-out fee, no hidden charges - just honest, skilled work from a local professional you can rely on.

Common questions about the mobile auto locksmith service across London.
Can you cut and program a new car key on the spot?
Bullard Locks provides on-the-spot car key cutting and programming from a fully equipped mobile workshop. William carries dealer-level diagnostic and programming equipment, blank key stock, and precision key-cutting machinery for all major vehicle manufacturers. In most cases, a brand-new key is cut, electronically programmed to your vehicle's immobiliser, and fully tested within a single visit - typically 30 to 90 minutes. There is no need to have the car towed to a dealership or wait days for parts. Call 07809 887 883 for immediate availability across North and Central London.
What vehicle makes and models do you cover?
Bullard Locks covers all major vehicle manufacturers sold in the UK, including Ford, Vauxhall, BMW, Mercedes-Benz, Audi, Volkswagen, Toyota, Honda, Nissan, Peugeot, Renault, Citroen, Kia, Hyundai, Land Rover, Jaguar, Volvo, MINI, SEAT, Skoda, Fiat, and many more. William carries programming equipment that supports vehicles from the early 2000s through to the latest 2026 models, including proximity keys, smart keys, and keyless entry systems. If you are unsure whether your vehicle is covered, call 07809 887 883 - William can confirm immediately based on your make, model, and year.
How much does a replacement car key cost?
Replacement car key prices depend on the vehicle make, model, year, and key type. A basic transponder key for a common vehicle is typically less expensive than a proximity smart key for a premium brand. William provides a firm, fixed-price quote before any work begins - the price quoted is the only amount you pay. There is no call-out fee, no surcharge for evenings or weekends, and no hidden charges. In most cases, an auto locksmith replacement key costs significantly less than the equivalent from a main dealer, often saving 30-50% while being completed on the same day at your location.
How long does car key replacement take?
Most replacement car keys are cut and fully programmed within 30 to 90 minutes on site. Standard transponder keys for common makes like Ford, Vauxhall, and Volkswagen are typically at the faster end. More complex keys - such as proximity smart keys for BMW, Mercedes, or Audi - may take closer to 90 minutes due to the additional programming steps required. William works at your location, so there is no waiting for a tow truck or parts delivery. Once the new key is programmed, it is tested to ensure it starts the engine, locks and unlocks all doors, and activates any remote functions before the job is signed off.
I have lost all my car keys - can you still help?
Bullard Locks specialises in all-keys-lost situations, which is one of the most common reasons customers call. Even with no working keys at all, William can generate, cut, and program a completely new key set for most vehicles directly at your location. This involves reading the vehicle's immobiliser data, cutting a fresh key blade to match the locks, and programming the new transponder chip so the car recognises and starts with the replacement key. This service is often 30-50% cheaper than going through a main dealer and avoids the cost and inconvenience of having the vehicle towed to a dealership.
Do you repair and reprogram key fobs and transponders?
Bullard Locks handles all key fob and transponder issues, including faulty buttons, worn cases, dead transponder chips, battery replacement, and remote central locking faults. William also supplies and programs proximity keys and smart keys for keyless entry and push-button start systems. If your key fob has stopped locking or unlocking the car remotely, or the engine immobiliser no longer recognises your key, these problems are usually resolved within a single visit. Replacement fob cases and buttons are carried as standard stock, and reprogramming is done on-site using the same dealer-level equipment used by main franchised dealers.

L
Replaced the locks in my new home, super professional and friendly, also managed to resolve an issue with my door being difficult to close due to the original locking mechanism. Thank you!
E
Locksmith arrived within 10 minutes on a sunny Sunday afternoon and got us back into the flat within an hour. He tried his best to get in without replacing the lock but had to replace it in the end. Very friendly and efficient service at a very good price.
C
Real lifesaver, managed to lock ourselves out, turned up in 10 minutes in Crouch End and charged a reasonable fair for a Friday at 8:30pm! Door was opened without any damage. Great friendly guy too. I hope your chippy tea was still hot when you got home!
P
William was excellent. Came out promptly, clearly knows what he's doing. A really nice guy too! We'd called out another so called "locksmith" beforehand who turned out to be a right conman. When William turned up you immediately felt he was someone who could be trusted, and he managed to unlock the door without damaging anything. Highly recommend!
N
William picked up the call first time and was round my house within 15 minutes - after the wife and I locked ourselves out during the morning school run. Quick, prompt, has a car full of equipment and got us indoors within 15 minutes. Great value, nice guy. Recommend.
