A replacement car key without the original

Losing the last working key does not always mean recovering the vehicle to a main dealer. For many supported vehicles, the replacement process can be completed where the car or van is parked.

An all-car-keys-lost situation is different from copying a spare. There is no working key available to identify, decode or use during programming, so the exact vehicle system must be checked before the correct parts and procedure can be confirmed.

AG Locks starts with the registration, make, model, year, vehicle location and any information about the missing key. Depending on the vehicle, the replacement may involve identifying the correct blade profile, producing a mechanical key, preparing a compatible transponder or remote and programming it to the vehicle's immobiliser.

The aim is not merely to supply a key-shaped product. The finished key must be checked for physical operation, immobiliser recognition and the available remote or smart functions. Where the vehicle system permits it, previously lost keys may also be removed from the authorised key list for additional security.

What the service can include

More than simply supplying another key

The work required depends on the vehicle. A proper quotation should account for the replacement key, mechanical cutting, immobiliser programming, remote functions and the condition of the vehicle.

Check Your Vehicle
01 / SERVICE

All Keys Lost Assessment

Registration-based checks to identify the likely vehicle key system, compatible replacement options and the correct route before attendance.

Check compatibility
02 / SERVICE

Replacement Key Creation

A compatible replacement key, remote or smart key is prepared for the specific vehicle rather than supplied as an unverified generic part.

Discuss the key type
03 / SERVICE

Car Key Cutting

Where the vehicle uses a mechanical blade, the replacement is cut to operate the relevant door lock and ignition system.

Ask about key cutting
04 / SERVICE

Immobiliser Programming

The replacement transponder is programmed or learned to a supported vehicle so the engine recognises the new authorised key.

Check programming support
05 / SERVICE

Remote and Smart Functions

Compatible locking, unlocking and keyless functions are set up and tested where those features are supported by the replacement key and vehicle.

Check remote options
06 / SERVICE

Lost Key Security Check

On supported systems, the missing key may be removed from the vehicle's authorised key list during the replacement process.

How lost key replacement works

A few accurate details at the start allow the correct parts, equipment and procedure to be considered before the visit is arranged.

Start With a Call
01

Send the registration and location

Provide the registration, make, model, approximate year, exact postcode and whether the vehicle is safely accessible.

02

Confirm the missing key situation

Explain whether every key is missing, whether the key may have been stolen and what type of key or remote was previously used.

03

Receive vehicle-specific guidance

Compatibility, likely replacement type, attendance and pricing are considered from the actual vehicle details rather than a generic headline quote.

04

The replacement is created and tested

At the vehicle, the required key is cut and programmed where supported, then checked for starting, locking and available remote functions.

Why choose AG Locks

A clear route from stranded to moving again

An all-keys-lost job needs more than a cheap blank and a promise. The vehicle, key system, parts and programming route must all line up.

Mobile Service

The work is brought to the vehicle where practical, avoiding the immediate need to organise dealership recovery.

Vehicle-Specific Checks

The registration and key system are checked before the replacement route is proposed.

Cut and Program

Mechanical cutting and immobiliser programming are handled together where required and supported.

Functions Tested

The finished replacement is checked against the vehicle rather than handed over untested.

Replacement key pricing

Why an accurate price needs the registration

The cost of replacing a lost car key depends on the actual security system—not simply the manufacturer badge. Two vehicles from the same brand can require different key parts, access methods, programming procedures and labour.

Call with the registration and vehicle postcode. That produces a more useful quotation than a low headline figure that ignores the key type or programming route.

Get a Vehicle-Specific Quote

Make, Model and Year

The vehicle generation and immobiliser platform determine which replacement process is available.

Key or Remote Type

A basic transponder key, flip remote and proximity smart key use different parts and procedures.

Programming Route

Some vehicles support a straightforward diagnostic procedure; others require additional specialist work.

Vehicle Location

Attendance depends on the postcode, access, safety and whether there is suitable working space around the vehicle.

Lost car key FAQs

Answers before you arrange replacement

The registration is still needed for a definite answer, but these cover the questions customers usually ask after losing the final key.

For many supported cars and vans, yes. A replacement can be created, cut and programmed without an existing working key. The exact route depends on the make, model, year and immobiliser system.
AG Locks provides a mobile service and attends suitable vehicle locations within the service area. Call with the exact postcode and explain where the vehicle is parked so attendance can be confirmed.
Pricing depends on the vehicle, replacement key type, blade cutting, programming route, vehicle location and any additional security work. The registration is needed for a useful quotation.
Many compatible proximity and smart-key vehicles can be supported. These keys vary significantly by model, year, frequency and security platform, so compatibility must be checked first.
On supported vehicle systems, a missing key may be removed from the authorised key list during programming. This does not physically recover the key, but it may stop that key from starting the vehicle.
The available functions depend on the replacement supplied and the vehicle. The mechanical operation, immobiliser recognition and supported remote functions are tested as part of the completed work.
AG Locks supports many compatible vans as well as cars. Provide the registration and model details so the correct blade, transponder and programming route can be checked.
Yes. Photo identification and evidence that you are authorised to access the vehicle may be required before entry, key creation or programming work is completed.
Not unless compatibility has been confirmed. Keys with the same outer appearance can use different electronics, frequencies, transponders or blades and may not be usable on your vehicle.
Send the registration, make and model, approximate year, exact vehicle postcode, previous key style, whether every key is missing and whether the loss may involve theft.
