Auto Locksmith Leicester | 24/7 Emergency Car Locksmith Services
Almost everyone who calls us about a lost key says the same thing afterwards: they'd been meaning to get a spare. Cut and programmed while you still have a working key, a spare costs a fraction of an emergency all-keys-lost replacement — and turns a lost key into an inconvenience rather than a write-off day.
Cut and programmed by Mohamed Khalid Ali — a qualified mechanic with 15+ years in the motor trade. More about us
It isn't a discount, it's a genuinely different job.
With a working key in hand, we have a pattern to cut from and a reference the vehicle already accepts. Adding a second key to the immobiliser's list is usually a straightforward operation through the diagnostic port. The car is open, nothing needs decoding, and there's no urgency.
With every key lost, the job changes completely. The vehicle has to be opened with non-destructive entry first, the key data read from the car itself rather than copied, sometimes at module level, and the blade cut to code rather than to a pattern. More time, more equipment, and usually at whatever hour it happened.
That's the entire argument for doing it early. Same key, same car, dramatically different job — and the only variable is whether you still have one that works.

Some situations make a single key a genuine risk rather than a minor gamble:
The obvious one, and the most ignored. A single key means one loss, one snap or one washing machine away from an emergency call-out and a much bigger bill.
Second-hand cars very often come with one key, and you can't know how many others exist or who has them. A spare plus erasing unknown old keys is worth considering together.
A couple sharing one key, or a family car passed between people, is a lockout waiting for a bad morning. Two keys removes the problem entirely.
Rounded cuts, a bent blade, or needing to jiggle it to turn. Cutting a spare from it now, while it still works, is far better than after it snaps.
A stranded driver mid-round costs far more than a spare key ever will. A second key kept at base is straightforward insurance.
Keys get taken, posted through things and hidden with remarkable creativity. Anyone who's been through it already knows why this one's on the list.
A spare doesn't always have to match your original exactly, and there's usually a cheaper sensible option worth knowing about:
Ring with your make, model and registration and we'll tell you which of these your vehicle actually supports — not every option exists on every car.
Planned, unhurried, and done at your vehicle whenever suits you.
Make, model, year and registration, plus a photo of your existing key if you can. We'll confirm the options and price.
Because it isn't an emergency, we can work around you - at home, at work, or wherever the car sits during the day.
Blade cut from your existing key, transponder programmed to the immobiliser, and remote functions set up if the key has them.
Both keys checked in the door, ignition and boot before we leave, so you know the spare genuinely works rather than hoping it will.
A spare key only helps if it's somewhere you can get to it and a thief can't:
More on protecting the vehicle itself: vehicle security.
What's possible varies by manufacturer — which key types are available, whether a simpler emergency key can be programmed, and how the spare is added to the immobiliser. Pick your make, or ring with the registration.
Across Leicester, at a time that suits you rather than at 2am in a car park.

Excellent service from K Stone locksmith, very nice bloke who clearly knows his trade well. Supplied and programmed a new key fob for my 2018 335D very quickly and explained the whole process, the fob is very high quality for an aftermarket key can hardly tell a difference in style or operation. Offers very competitive pricing and in the end he was more than half the price of anyone else i received quotes from. Highly recommendPosted on Google![]()

khalid did exactly as he said he would and I would recommend him to anyone needing this service. He quoted a price and time, stuck to both and did an amazing job; he got my daughter back on the road quickly and he’s a nice guy too. cracking service and a huge thank you from a worried dad. You can trust him to help you which is sometimes all we need. Very professional and polite.Posted on Google![]()

K Stone Auto Locksmith is an absolute lifesaver, and I cannot recommend his services highly enough. He attended at 9pm on a Friday night and arrived within 30 minutes. A new key was cut and programmed efficiently and without any issues. A sincere thank you from DHP Roofing Services.Posted on Google![]()

Arrived within 30mins. Job done in less than 5mins. Quick and professional Lifesaver! Thank you!!!
Meaningfully cheaper, because it's a genuinely different job rather than a discount. With a working key we have a pattern to copy and a reference the car already accepts. With every key lost, the vehicle has to be opened, the data read from the car itself and the blade cut to code - more time, more equipment, and usually out of hours.
It makes the job simpler and cheaper, yes. If you still have a working key, bring it out to the car. Spares can be produced without one, but at that point it's an all-keys-lost job rather than a spare.
On many vehicles, yes. A simpler key that starts the car but has no central locking buttons is often available and is perfectly sensible for a backup kept at home. Ring with your registration and we'll confirm whether yours supports it.
Usually, yes. Programming additional keys during the same visit avoids a separate call-out later, so the cost per key is lower and you're never back down to one.
Adding a spare to a straightforward system is generally quick, though it varies by vehicle and key type. You'll get a realistic estimate on the phone before we come out.
Yes, the same as any key job. Usually the V5C showing you as registered keeper, photo ID matching the address, and insurance or purchase paperwork where relevant. Any locksmith who doesn't check should worry you.
Getting a spare is sensible, and it's also worth asking about erasing keys you can't account for. On many vehicles, previously programmed keys can be deleted from the immobiliser so they'll no longer start the car.
Somewhere you can reach it but a thief can't - not in the car, not by the front door, and in a signal-blocking pouch if it's a keyless fob. Avoid keeping it with anything that shows your address.
Yes - Transit, Vivaro, Transporter, Sprinter, Trafic and more, plus agricultural equipment. For a work vehicle a spare kept at base is straightforward insurance against a stranded driver.
Call with your make, model and registration for an honest price on a spare — no call-out fee, ever.
