Car Key Fob Replacement & Repair – Mobile

Key fob not working or need a replacement? Call 07777 676261 or message us on WhatsApp. We repair and replace car key fobs at your location for all makes — usually within 30 minutes of arriving.

A faulty or broken key fob is more than an annoyance — if the buttons have stopped working or the case has cracked, you can be left struggling to lock, unlock, or even start your car. Royale Car Keys repairs and replaces key fobs on-site across London, Kent, Essex, Surrey, and Sussex. We come to you, sort the fob at the roadside or on your driveway, and make sure it's properly paired with your vehicle before we leave — 24 hours a day.

What We Do With Key Fobs

Depending on what's wrong, we can repair your existing fob or supply and program a new one:

• New replacement fobs — supplied, cut, and programmed for your exact make and model.
• Fob repairs — worn or unresponsive buttons, cracked cases, and damaged internal boards.
• Battery replacement — often the simplest fix when a fob suddenly stops responding.
• Reprogramming — re-pairing a fob that's lost its connection to the car.
• Keyless smart fobs — proximity fobs for push-to-start cars, including high-security systems.

We work on all major manufacturers, including Ford, Vauxhall, BMW, Mercedes, Audi, Renault, Nissan, Toyota, Kia, and Hyundai, plus many more.

Before You Replace It — Is It Just the Battery?

Quite often a fob that's "died" simply needs a new battery, or has a single worn button rather than a full fault. Before quoting a replacement, we'll always check the simplest causes first — it's cheaper for you and it's the honest way to work. If your fob has stopped working and you'd like to try a few things yourself first, our guide walks through the quick checks: Car Key Fob Not Working? 7 Things to Try.

How It Works

1. Call us. Tell us your make, model, year, and what the fob is doing. We give you a price before we set off — no surprises.
2. We come to you. A mobile technician arrives, usually within 30 minutes, with the parts and programming equipment needed on-site.
3. We repair or replace. We fix the fault or supply and program a new fob, then test it works with your car.
4. You're sorted. Pay on completion by card, cash, or bank transfer. Any new fob is covered by our 2-year warranty.

How Much Does It Cost?

Key fob repairs and replacements depend on your vehicle and what's needed — a battery or button repair is at the lower end, while a new programmed smart fob for a modern car costs more. We confirm the full price, including call-out and labour, before we begin, so there are no hidden extras. See our pricing page for our standard rates, or call for a quote on your exact fob.
