A Replacement Key Is Two Jobs, Not One
Most people picture key replacement as cutting a piece of metal. On any car built in roughly the last twenty-five years, that's only half of it.
Cutting shapes the physical blade so it turns in the door and ignition. That might be a traditional edge-cut blade or, on most modern cars, a laser-cut (sidewinder) blade milled along the flat of the key.
Programming is the part that actually gets you moving. Inside the key is a transponder chip carrying a unique code. Your car's immobiliser reads that code when you turn the key or press start, and if it doesn't recognise it, the engine won't fire — even though the key physically turns.
That's why a blade-only copy may open the door but won't start most immobiliser-equipped vehicles unless the transponder is also correctly programmed. Both halves have to be done, and the programming half needs diagnostic equipment matched to your manufacturer.

Which Kind Of Key Do You Have?
The type of key makes the biggest single difference to what a replacement costs and how long it takes. If you're not sure which you've got, send a photo over WhatsApp and we'll tell you.
Basic Blade Key
No electronics at all - just a cut piece of metal. Found on older vehicles, typically pre-1998, and on some vans and agricultural machinery. Quickest and cheapest to replace.
Transponder Key
Looks like an ordinary key but has a chip in the plastic head. The car won't start unless the chip is programmed to the immobiliser. Standard on most cars from the late 1990s onward.
Remote / Flip Key
Combines a cut blade with buttons for central locking, often folding into the fob. Both the blade and the remote functions need setting up, so there's more to the job.
Smart / Proximity Key
Keyless entry and push-button start - the key stays in your pocket. The most complex and most expensive to replace, because the fob is a genuine electronic module rather than a key with buttons.

WhatsApp UsLost All Your Keys, Or Still Have One?
This single question changes the job more than the make of car does, and it's the first thing we'll ask on the phone.
If you still have a working key
This is the straightforward version. The existing key gives us a reference to work from, the car is already accessible, and adding a second key to the system is usually quick. If you're reading this before losing anything, this is the cheap moment to act — see spare car keys.
If every key is lost ("all keys lost")
More involved. We first have to gain non-destructive entry to the vehicle, then read key data directly from the car rather than copying an existing key, sometimes at module level. On some vehicles previously lost keys can also be erased from the system, so a key someone else has found no longer starts your car.
Both are routine work. The all-keys-lost version simply takes longer and costs more, and anyone quoting you a single price without asking which situation you're in isn't quoting accurately.
How A Replacement Key Job Runs
Start to finish, usually within a single visit.
You Call
Give us the make, model, year and registration, plus whether you have any key at all. We'll identify the key type and quote before setting off.
We Come To You
Home, work, car park or roadside — anywhere in Leicester, with everything needed carried in the van.
Cut & Program
The blade is cut to your lock, then the transponder is programmed to your immobiliser using manufacturer-level equipment.
Tested Before We Leave
We check the key locks, unlocks and starts the engine, and that any remote buttons work, before the job is finished.
Proof Of Vehicle Authority — And Why We Check It
Every legitimate auto locksmith will ask you to show you're entitled to a key for the vehicle before cutting one. It takes a minute, and it's the single thing standing between a professional trade and an extremely convenient car theft service.
Usually that means a combination of documents rather than any single one. The V5C identifies the registered keeper and the vehicle's details rather than proving legal ownership on its own, so we'll normally want it alongside photo ID matching the address, and insurance or purchase paperwork where relevant. If the car is a company vehicle, a lease car, or recently bought and not yet transferred, ring ahead and we'll talk through what works.
If a locksmith doesn't ask, that should worry you rather than please you. It means they'd cut a key to your car for a stranger too.
- V5C showing you as registered keeper
- Driving licence matching the address
- Insurance certificate for the vehicle
- For company or lease cars, a letter of authority
- Recently purchased? Bring the receipt or sale documents
Why Nobody Can Quote You Accurately Without Details
Car key replacement costs vary genuinely and substantially. These are the things that actually move the number:
- Key type — a basic blade key and a smart proximity key are worlds apart in both parts cost and programming time.
- All keys lost or not — needing entry and reading data from the car is more work than copying an existing key.
- Make and model — some manufacturers are straightforward through the diagnostic port, others need module-level work.
- Age of the vehicle — newer isn't automatically harder, but newer security systems often are.
- How many keys you want — a second key programmed in the same visit costs far less than coming back for it later.
Our pricing sits deliberately mid-range: rarely the cheapest quote in Leicester, never the most expensive. You get a clear figure on the phone before we set off, and it doesn't change on arrival unless something genuinely different turns up — in which case we tell you before doing any work.
Compared with a main dealer, a mobile replacement is usually cheaper and faster, because there's normally no recovery to a workshop and no wait for a key to be ordered in.

Car Key Replacement FAQs
Can you replace a car key if I've lost every copy?
Yes. This is called an all-keys-lost job. We gain non-destructive entry to the vehicle, then read key data directly from the car rather than copying an existing key. It takes longer than adding a spare, but it's routine work.
How long does a replacement car key take?
Many jobs are completed within the same visit. Straightforward transponder keys are usually quicker, while all-keys-lost situations and smart keys take longer. You'll get a realistic timeframe on the phone before we set off.
Do I need to have the car towed anywhere?
No. The whole job is done at your vehicle, wherever it is - home, work, a car park or the roadside. That's the main advantage over a dealership, which normally requires the car to be recovered to them.
Will a key cut at a shoe bar or key kiosk work?
A blade-only copy may well open the door, but most immobiliser-equipped vehicles won't start unless the transponder chip is also programmed to the car. Some outlets can clone certain transponder types, but many cannot, so it's worth checking exactly what you're being sold.
What proof do I need that the car is mine?
Usually a combination: the V5C showing you as registered keeper, photo ID matching that address, and insurance or purchase paperwork where relevant. For company or lease vehicles, a letter of authority. Any locksmith who doesn't check should worry you.
Can you erase a lost key from my car?
On many vehicles, yes. If your lost key has fallen into the wrong hands, deleting it from the immobiliser means it will no longer start the car. Worth asking about if the key was lost somewhere identifiable, like with a wallet.
Is a locksmith cheaper than a main dealer?
Usually yes, and often faster. A dealer replacement typically means recovering the vehicle to them and waiting for a key to be ordered, while most of our work is completed at the roadside.
Do you replace keys for vans and commercial vehicles?
Yes - Transit, Vivaro, Transporter, Sprinter, Trafic and more, plus agricultural equipment that many locksmiths won't take on.
Should I get a second key at the same time?
It's usually much cheaper to program two keys in one visit than to come back later for a spare. If the budget allows, it's the sensible moment to do it.

Worth knowing: the cheapest key job is the one you never need. According to Thatcham Research, the UK's independent vehicle security testing body, storing a keyless fob in a signal-blocking pouch significantly reduces relay-theft risk. Full guide: Does Tin Foil Block Car Key Signals?
