Car Lock Set Change – Mobile Locksmith

Need your car locks changed or replaced? Call 07777 676261 or message us on WhatsApp. We change car lock sets at your location for all makes — usually within 30 minutes of arriving.

There are times when a new key isn't enough and the locks themselves need changing — after a theft or break-in, when keys have been lost or stolen and you want to be certain no one else can get in, or when a lock has worn out or been damaged. Royale Car Keys changes car lock sets on-site across London, Kent, Essex, Surrey, and Sussex. We come to you, replace the locks, and supply keys to match — so your old keys no longer work and your vehicle is secure again, 24 hours a day.

When You Might Need a Lock Set Change

Replacing the lock set — rather than just cutting a new key — makes sense in several situations:

• After a break-in or attempted theft — where a lock has been forced or damaged.
• Lost or stolen keys — when you want to guarantee the missing keys can never open the car.
• Worn or seized locks — door barrels that no longer turn smoothly or have failed.
• Buying a used vehicle — for peace of mind that no previous owner holds a working key.
• Damaged door or boot locks — replacing the faulty barrel and matching it to your key.

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

New Locks, Keys to Match

When we change a lock set, we supply and fit new locks and provide keys cut and programmed to match them. The result is a vehicle that's fully secure again — any previously lost or stolen keys are rendered useless, because they no longer fit the new locks. Where it's possible to match the new locks to your existing key so you don't have to carry two, we'll let you know; where the situation calls for an entirely fresh set, we'll explain why.

How It Works

1. Call us. Tell us your make, model, and why you need the locks changed. 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 locks, parts, and programming equipment needed on-site.
3. We change the lock set. We fit the new locks and supply keys cut and programmed to match.
4. You're secure again. Pay on completion by card, cash, or bank transfer. The work is covered by our 2-year warranty.

How Much Does It Cost?

The cost of a lock set change depends on your vehicle and how many locks need replacing — a single door barrel is at the lower end, while a full set is more involved. 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 vehicle.

Worried About Theft? Consider an Immobiliser

If you're changing your locks because of theft or a break-in, it's worth thinking about extra protection too. A Ghost 2 or CAN Phantom immobiliser stops a thief starting your car even if they have a key or clone the signal. See our Ghost 2 immobiliser service, or read our comparison: Ghost 2 vs CAN Phantom.

Frequently Asked Questions

Why would I change the locks instead of just getting a new key?
Changing the locks guarantees that any lost or stolen keys can no longer open your car — a new key alone doesn't do that. It's also the answer when a lock is damaged, worn, or has been forced in a break-in.

Will my old keys still work after a lock change?
No — that's the point. Once we fit the new locks, any previous keys no longer fit, so anyone holding a lost or stolen key can't get in. We supply new keys cut to match.

Can you do this at my location?
Yes. We're fully mobile and change lock sets at your home, workplace, or roadside. We don't tow your vehicle.

How much does a lock set change cost?
It depends on your vehicle and how many locks need replacing. We confirm the full price, including call-out and labour, before we start work.

How long does it take?
It varies by vehicle and how many locks are involved. We'll give you a realistic timeframe when you call with your make and model.

Are you available at night and on weekends?
Yes — 24 hours a day, 365 days a year, including bank holidays.
