Remote key fobs have become the standard way to interact with your vehicle — locking and unlocking doors, opening the boot, and in keyless-entry vehicles, starting the engine without physically inserting a key. When your key fob fails — whether through damage, water ingress, battery failure beyond replacement, or simply being lost — you're not just locked out of convenience features; on many modern vehicles with push-button start, you may not be able to drive the car at all. Excalibur Auto Locksmiths carries replacement key fobs and the programming equipment to match them to your vehicle, all from our mobile workshop across the North West.
Main dealers charge a premium for key fob replacement because they supply OEM (original equipment manufacturer) parts with their own profit margin and programme them in-house. Many drivers are shocked to be quoted £200–£400 for what seems like a simple remote control. The reality is that the fob itself — which contains the transponder, the RF transmitter, and the emergency blade key — can be sourced at a fraction of dealer cost, and programming is a routine process with the right tools. Excalibur consistently offers key fob replacement at 40–60% less than main dealer pricing.
When you call, Ian or Adam will ask for your vehicle's make, model, year, and frequency specification to confirm we have the correct replacement fob. On arrival, we program the new fob to your vehicle using the appropriate method — which varies by manufacturer, ranging from a simple sequence of button presses and ignition cycles to full OBD-level programming. For vehicles using rolling-code or crypto-encrypted remotes, we use our dealer-grade diagnostic tools to synchronise the new fob securely. We also programme the mechanical blade key within the fob to your locks where required.
Over 30 years working across the North West, Ian and Adam have programmed key fobs for thousands of vehicles. Brands handled include Ford, Vauxhall, Volkswagen, Audi, BMW, Mercedes-Benz, Renault, Toyota, Honda, Nissan, Peugeot, Citroën, Hyundai, Kia, SEAT, Škoda, Land Rover, Volvo, and many more. Whether you need a replacement for a lost fob or an additional fob programmed as a spare, Excalibur provides a same-day service wherever your vehicle is parked across the North West region.

Source and Supply Replacement Fob
We supply the correct quality replacement fob from our mobile stock or same-day sourcing. We advise on both OEM and quality aftermarket options.
Programme via OBD or Sequence Method
Using the correct method for your vehicle — OBD programming, dealer tool sequence, or manufacturer-specific button programming — we sync the new fob to your car.
Cut Blade Key if Required
If your fob includes an emergency mechanical blade key, we cut it to your door and ignition lock profile using our mobile key-cutting equipment.

How Much Does Remote Key Fob Replacement Cost?
The cost of remote key fob replacement depends on your vehicle's make, model, and the specific key type required. Excalibur is consistently 40–60% cheaper than main dealer pricing because we don't carry dealer overheads, and we use quality compatible components rather than OEM parts at manufacturer prices.

Remote Key Fob Replacement — Frequently Asked Questions
Often a key fob that appears dead simply needs a new battery — which is inexpensive and something you can do yourself if you're comfortable opening the fob. If a fresh battery doesn't restore function, the fob's internal circuit board may be damaged, the signal buttons may have failed, or the transponder chip may have been disrupted. In those cases, replacement and reprogramming is usually more cost-effective than attempting a repair. Call us and describe the symptoms — we can advise whether a new battery might resolve it or whether a replacement is needed.
The opposite — we come to you. All key fob programming is carried out at your vehicle's location. We need access to the vehicle because the programming process communicates with the car's ECU directly. No towing, no workshop visit, no disruption to your day.
No. Most vehicles support multiple programmed fobs simultaneously, and adding a new fob does not overwrite existing ones. The only exception is certain older manufacturers that require all fobs to be programmed in a single session — in which case we programme all your fobs at the same time and advise you accordingly before starting.
Water damage varies in severity. Fresh water that was dried out quickly may leave the fob functional once the battery is replaced and any corrosion cleaned from contacts. Prolonged immersion or salt water exposure often causes irreparable internal damage. If you're not sure, bring the fob when we arrive and we'll assess it — if there's a chance of salvage we'll tell you honestly rather than pushing you towards a more expensive replacement.
Yes, in many cases — but compatibility is critical. The fob must match the correct frequency, chip type, and protocol for your specific vehicle. Many online listings describe fobs as universal or compatible when they may not be. If you've already purchased one, bring it and we'll assess compatibility. If it's suitable, we'll programme it. If it isn't, we can supply the correct alternative.
