Getting a Replacement Car Key Without the Original
A replacement car key is made without the original by an auto locksmith who cuts a new blade to the locks of the vehicle and programs a new transponder to its immobiliser, at the place the vehicle stands.
Inta-Lock Car Key Guides. Updated October 2026.
The original key is a convenience for the job and not a requirement. The vehicle holds the two things the key held, the cut pattern of its locks and the immobiliser that accepts a transponder, so the new key is built from the vehicle and nothing is copied.
The owner supplies the registration, the vehicle details and evidence of identity and authority to request the work. The missing original is then dealt with as a security matter, because a key that exists somewhere still belongs to the car until it is removed from the immobiliser memory.
Is a Car Key Replaced Without the Original?
Yes, a car key is replaced without the original, because the new key is made from the vehicle and not from another key.
A copy and a replacement are two different jobs. A copy starts from a key in the hand. A replacement with no original starts from the car, which carries its own locks and its own immobiliser.
The answer holds for a key that is lost, stolen or snapped. The make, the model and the year decide the method, and whether the vehicle is among the supported vehicles is confirmed on the call.
How Is a Key Made With No Original to Copy?
A key with no original to copy is made in two parts, a blade cut to the locks of the vehicle and a transponder programmed to the immobiliser of the vehicle.
The blade is the mechanical part. Its cuts match the locks of one car. With no original to trace, the cuts come from key data requested against the vehicle identification details, or from decoding a lock on the vehicle where that is required.
The transponder is the electronic part. It is a small chip inside the head of the key, and the immobiliser checks it each time the ignition is switched on. A blade with no programmed transponder turns the lock and leaves the engine stopped. The new transponder is programmed to the immobiliser at the vehicle, on supported vehicles.
Remote buttons and a keyless function sit on top of those two parts, and they are programmed to the vehicle where the key carries them.
What Takes the Place of the Original Key?
The vehicle and its owner take the place of the original key, and each part of the new key has its own source when there is nothing to copy.
| Part of the new key | What a copy takes from the original | Where it comes from with no original | What the owner supplies |
|---|---|---|---|
| The cuts of the blade | The cut pattern of the blade in the hand | Key data requested against the vehicle identification details, or a lock on the vehicle decoded where that is required | The registration and access to the vehicle |
| The transponder | A working key is present while the further key is added | A new transponder programmed to the immobiliser at the vehicle, on supported vehicles | The vehicle itself, at the place it stands |
| The remote buttons | The remote type of the key in the hand | The remote type matched to the make, the model and the year | The make, the model and the year |
| The keyless function | The keyless key in the hand as the pattern | A keyless key programmed to the vehicle, on supported models | Whether the engine starts on a button or on a turned key |
| The right to have a key made | Nothing, a key in the hand does not show who the keeper is | A check of identity and authority to request the work | The V5C and photo identification as common examples |
The table shows the source of each part, not its cost. A quote for the key is agreed before work begins, once the vehicle and the key type are known.

Call Matt on 0116 442 2084What Does a Locksmith Ask For Without the Original?
Four details are asked for when a car key is made without the original, and three of them are given on the first call.
- The registration. The registration identifies the vehicle, and with it the make, the model, the year and the key type.
- The place and state of the vehicle. The address or car park where the vehicle stands, and whether it is locked. A locked car with no key is opened by non destructive entry before the key is made.
- The key that is missing. A plain key, a remote key or a keyless key, and whether it is lost, stolen or broken. A stolen key changes the security step that follows.
- Identity and authority. Identity and authority to request the work are checked before a key is made. The V5C vehicle log book, which names the registered keeper, and photo identification are common examples, and what applies is confirmed on the call.
A V5C that went missing with the key is replaced by DVLA. GOV.UK states that a replacement log book usually arrives by post within 5 to 7 working days. Say on the call that the log book is missing, and the documents that apply are confirmed on the call.
The check exists because a key made with no original starts a car for whoever holds it. Access to security related repair information for vehicles is controlled for the same reason. SERMI is the scheme that sets the terms of that access for independent operators, and Inta-Lock is SERMI accredited.
What Happens at the Vehicle on the Visit?
Five steps take a car with no original key from the phone call to a working key in the hand.
- Call Matt on 0116 442 2084 with the registration, the place the vehicle stands and the key that is missing. A quote is agreed before work begins.
- Matt is with you within the hour in Leicester, and the same day across Leicestershire. Identity and authority to request the work are checked before a key is made.
- A locked vehicle is opened by non destructive entry before the key is made.
- The blade is cut to the locks of the vehicle, and the transponder, with the remote where the key carries one, is programmed to the immobiliser.
- The finished key turns the door lock and the ignition, and the immobiliser accepts its transponder, so the engine starts on the new key.
The same work, with each lost key situation and its security step, is set out on the service page for every car key lost in Leicester.
What Happens to the Original Key That Is Missing?
The original key that is missing stays a working key of the car until it is removed, so missing electronic keys are removed from the immobiliser memory where the vehicle supports it.
Removal acts on the electronic part of the key. A removed transponder is refused by the immobiliser, and the engine stays stopped for that key. A mechanical blade still turns a physical lock unless that lock is changed or rekeyed.
The same step applies to a car bought with fewer keys than it left the factory with. Thatcham Research advises the owner of a second hand vehicle bought with one working key to have the missing key deleted and a spare added, in its guidance on car security. The police give the matching advice to reprogramme the keys of a second hand car, in the Metropolitan Police advice on preventing vehicle theft.
The theft of a key is reported to the police. Say on the call that the original was stolen, and what applies to the locks of the vehicle is confirmed on the call.
Does the Key Type Change the Job?
Yes, the key type changes the job, because each type adds a part to cut or to program when no original exists.
- A plain mechanical key. A plain mechanical key is a blade with no chip. The job is the cut alone, and it applies to older vehicles built before immobilisers were fitted.
- A transponder key. A transponder key is a blade with a chip in its head. The blade is cut and the chip is programmed to the immobiliser.
- A remote key. A remote key is a transponder key with locking buttons. The buttons are programmed to the central locking as a further step.
- A keyless key. A keyless key starts the engine on a button while it sits in a pocket. It is programmed to the vehicle on supported models. Its emergency blade fits the door lock, and whether that blade is cut with the key is confirmed on the call.
The registration identifies the vehicle, so an owner who does not know the type of the original key gives the registration, and the key type is confirmed on the call.
What Else Matters When No Original Key Exists?
Four questions sit beside the car key made without the original, and each one belongs to a page of its own.
How Does a Key With No Original Differ From a Spare Key?
A key with no original is built from the vehicle after the last key is gone, while a spare key is made beside a key that still works. The spare is the opposite situation and the smaller job.
The service for spare car keys in Leicester covers a second key cut and programmed while the first one still starts the car.
What Does the Identity and Authority Check Cover?
The check before a key is made is wider than one document. The registered keeper, a family member, a company driver and a buyer waiting for a log book each stand in a different position, and the article on how locksmiths verify car ownership takes each one in turn.
What Happens in the First Hour After the Loss?
A key with no original often begins as a key that is only mislaid. The search, the report of a theft and the call order are covered in the guide to what to do when car keys are lost, which comes before the decision to have a new key made.
Is the Key Made by a Locksmith or a Dealership?
Both an auto locksmith and a dealership supply a key when the original is gone. They differ in where the work happens and in what each asks of the owner, and that comparison is made in auto locksmith or dealership.
A car key with no original is made at the vehicle in Leicester, and the call to Matt is answered 24 hours a day.
Frequently Asked Questions
Does the car have to be towed when there is no original key?
No, a car with no original key stays where it stands, because the key is cut and programmed at the vehicle on supported vehicles.
Inta-Lock is a mobile auto locksmith, and the key work is carried out at the place the vehicle stands.
How much does a car key cost without the original?
The cost of a car key without the original is quoted for the individual vehicle, and a quote is agreed before work begins.
A keyless key raises the figure against a plain transponder key. A locked car adds the entry work. Whether removal of missing keys from the immobiliser memory is included is confirmed on the call. No price list is published.
How long does it take to make a key with no original?
The time to make a key with no original depends on the make, the model, the year and the key type, and it is confirmed on the call.
Matt is with you within the hour in Leicester, and the same day across Leicestershire.
Is the VIN enough to get a car key made?
No, the VIN alone is not enough to get a car key made, because the VIN identifies the vehicle and not the person asking for the key.
Identity and authority to request the work are checked as well, and the transponder is programmed at the vehicle itself.
What if the V5C is lost along with the key?
A V5C lost along with the key is replaced by DVLA, and the documents that apply to the key work are confirmed on the call.
The V5C and photo identification are common examples of what is checked, not the only route.
Does the original key work if it turns up later?
An original key removed from the immobiliser memory does not start the engine when it turns up later, and its blade still turns the locks.
Whether a found key is programmed back to the vehicle is confirmed on the call for the model concerned.
