Auto Locksmith or Dealership for a Replacement Key
An auto locksmith is the route for a replacement key made at the car where it stands, and a dealership is the route for a model whose key system the manufacturer keeps inside its own network.
Inta-Lock Car Key Guides. Updated October 2026.
Both routes end with a key that is cut to the locks and programmed to the immobiliser of the car. They differ in where the work happens, in what each one asks of the owner and in the checks that stand behind the people doing the work. Place matters most when every key is lost, because a car with no key does not drive to a site.
This comparison states no price and no waiting time for a dealership, because both change from one dealership and one model to the next. It sets out the paperwork, the two security checks, the three situations that belong with the dealer network and the questions that settle the choice on one phone call.
Is an Auto Locksmith or a Dealership the Right Route?
An auto locksmith is the right route where the key is made at the car and the model is a supported vehicle, and a dealership is the right route where the manufacturer keeps that key system inside its network.
A mobile auto locksmith brings the key cutting machine, the programming equipment and the key stock to the vehicle. A dealership is a fixed site that sells and services the vehicles of the manufacturer it represents.
Three facts about the car settle the choice. The first is whether the car drives. The second is whether a working key remains. The third is whether the model is a supported vehicle, which is confirmed on the call. Where all three are yes, both routes are open and the choice comes down to place and paperwork.
Where Does Each One Make the Replacement Key?
An auto locksmith makes the replacement key at the vehicle, on a drive, at a workplace or at the roadside, and a dealership makes or supplies the key at its own site.
Place matters most when the car does not drive. A car with every key lost stays where it stands until a key exists. Where a dealership programmes the key on its premises, the car is moved to the site first. Mobile work removes that step, because the key is cut and programmed where the car is parked.
Inta-Lock is a mobile auto locksmith serving Leicester and Leicestershire. Matt is with you within the hour in Leicester, and the same day across Leicestershire. The service page for replacement car keys in Leicester sets out how a lost, stolen, broken or worn key is replaced at the vehicle.
How Do an Auto Locksmith and a Dealership Compare?
An auto locksmith and a dealership compare on seven points, and each point is a fact about place, paperwork, checks or cover, not about the figure on an invoice.
| Point of comparison | Mobile auto locksmith | Dealership |
|---|---|---|
| Where the key is made | At the vehicle, wherever it is parked | At the dealership site |
| How a car with no working key reaches the work | It stays where it stands | It is moved to the site where the key is programmed on the premises |
| What the owner provides | The registration, the make, the model and the year, the place the car stands, and identity and authority to request the work | The documents that dealership sets, confirmed with the dealership before the visit |
| The check on the person asking for a key | Identity and authority to request the work are checked before key work begins | Set by the dealership and the manufacturer it represents |
| The check on the people doing the work | Accreditation held by the locksmith. Inta-Lock is SERMI accredited, and Matt is Enhanced DBS checked, NCFE qualified and an NNAL member | The franchise the dealership holds from its manufacturer |
| Which vehicles are covered | Supported vehicles across a range of makes, confirmed on the call | The makes that dealership represents |
| How the figure is set | A quote is agreed before work begins | Quoted by the dealership on request |
The table leaves out price and waiting time on purpose. Both differ from one dealership to the next and from one key to the next, so neither is stated here as a general fact about a dealership or a locksmith.

Call Matt on 0116 442 2084What Does Each One Need From the Owner?
Each one needs two things from the owner, details that identify the vehicle and evidence that the person asking has the right to a key for it.
- The registration number. The registration number identifies the vehicle. With the make, the model and the year, it tells the locksmith which key and which key system the car carries.
- The V5C. The V5C is the vehicle registration certificate, also called the log book, and it names the registered keeper. A missing V5C is replaced through DVLA, as set out on the GOV.UK page for a vehicle log book.
- Photo identification. Photo identification shows that the person standing at the car is the person named on the paperwork.
- Authority for a car kept by someone else. Authority is the permission of the keeper where the car belongs to a company, a lease firm or another person.
- The keys still held. The number of keys still held decides the job. One working key makes the work a spare key, and no key makes it a replacement from nothing.
At Inta-Lock, identity and authority to request the work are checked before key work begins. The V5C and photo identification are common examples, and what applies is confirmed on the call. DVLA states that the V5C does not prove who owns a vehicle, which is why the check covers identity and authority and not the log book alone. A dealership sets its own list, and that list is confirmed with the dealership before the visit.
What Security Checks Protect a Replacement Key?
Two security checks protect a replacement key, the check on the person asking for the key and the check on the people who make it.
The first check stops a key being made for someone with no right to the car. It is the identity and authority check set out above.
The second check covers the people who hold the equipment. SERMI is the scheme under which independent operators are approved, and their employees authorised, to access security related repair and maintenance information for motor vehicles. Approval is carried out by a conformity assessment body, and each authorised employee holds a personal security certificate. Inta-Lock is SERMI accredited.
A dealership works under the franchise of its manufacturer, which is a separate arrangement from the scheme for independent operators.
What Changes When Every Key Is Lost?
Every key lost changes one thing above all, the car no longer drives, so the place where the key is made decides whether the car moves at all.
With no key, the car is opened first, a new blade is cut and the new key is programmed to the immobiliser. A mobile auto locksmith carries out each stage at the vehicle on supported vehicles. A dealership that programmes keys on its premises receives the car on a recovery vehicle.
A lost key is still somewhere, so security is part of the job. During replacement, missing electronic keys are removed from the immobiliser memory where the vehicle supports it. A mechanical blade still turns a physical lock unless that lock is changed or rekeyed.
When Is the Dealership the Right Route?
The dealership is the right route in three situations, a model outside supported vehicles, a key fault the manufacturer covers, and an agreement that names the dealer network.
- A model outside supported vehicles. A model outside supported vehicles is one whose key system the locksmith does not hold access to. Whether a model is supported is confirmed on the call.
- A key fault the manufacturer covers. A key fault the manufacturer covers is one handled under a recall or under the cover sold with the car. That cover is claimed through the dealer network.
- An agreement that names the dealer network. Where a lease or finance agreement names the dealer network for keys, that agreement decides the route. The firm named on the agreement confirms which route it accepts.
Outside those three situations the choice is open, and place decides most cases. Garages and dealers have referred key work to Inta-Lock since 2021.
What Else Shapes the Choice of Provider?
Four questions sit beside the choice of provider, and each one belongs to a page of its own.
How Does a Spare Key Differ From a Replacement Key?
A spare key is made while one key still works, and a replacement key is made because a key is lost, stolen, broken or worn. The car still drives on the working key, so nothing forces the choice of provider.
A second key made in advance means a later loss leaves the car with a key that still starts it. That work is set out under spare car keys in Leicester.
What Moves the Cost of a Replacement Key?
The cost of a replacement key moves with the key type, the make, the number of keys still held and the place the car stands. No figure for either route is given on this page, and a quote is agreed before work begins. Each factor is explained in the guide to the cost of a replacement car key.
Which Work Does an Auto Locksmith Carry Out?
Key replacement is one part of the trade. Entry to locked cars, key cutting, key programming, lock repair and immobiliser work make up the rest, and the full range is covered under what an auto locksmith does.
Is a Key Sent by Post a Third Route?
A key by post is a third route that involves neither a visit to the car nor a visit to a dealership site. Inta-Lock offers keys by post, with Mercedes and Land Rover keys by post for supported models only.
A replacement key in Leicester is made at the vehicle, and the call to Matt is answered 24 hours a day.
Frequently Asked Questions
Does the car have to go to a dealership when every key is lost?
No, a car with every key lost does not have to go to a dealership where the model is a supported vehicle, because a mobile auto locksmith makes the key at the car.
A model outside supported vehicles is the exception, and whether a model is supported is confirmed on the call.
Which is cheaper, an auto locksmith or a dealership?
Neither route is cheaper as a general fact, because the figure depends on the key type, the make, the number of keys still held and the provider quoting.
A quote from Inta-Lock is agreed before work begins, and a dealership quotes its own figure on request.
Which is faster, an auto locksmith or a dealership?
The faster route depends on the model, the key held in stock and the provider, so no waiting time for a dealership is stated here.
Matt is with you within the hour in Leicester, and the same day across Leicestershire.

An auto locksmith checks identity and authority to request the work before key work begins.
The V5C vehicle registration certificate and photo identification are common examples, and what applies is confirmed on the call.
