Vauxhall Replacement Keys: The Ultimate Guide
By Iulian H., Lead Locksmith · Updated
City Locksmith London offers Vauxhall car key programming from £85 ex VAT and key duplication from £109 ex VAT, mobile across Greater London with no call-out fee. Across the market, a Vauxhall replacement key typically costs £90-£180 through a qualified auto locksmith or £200-£450 at a main dealer, depending on key type and model. On GM-era Vauxhalls (Corsa up to the E, Astra up to the K) a locksmith can read the security code from the car itself and cut and programme a key on-site in 30-45 minutes, even with all keys lost. On the Stellantis-era cars - Corsa F, Astra L, Mokka B, Grandland - all-keys-lost work needs manufacturer-level access, so ask any locksmith to confirm they can do it on your generation before they travel.
What Types of Vauxhall Replacement Key Are There?
Non-Remote Keys (Basic Blade Keys)
The most basic type: a metal blade with a transponder chip in the head, but no remote locking buttons. Found on older Vauxhall models. If the car has no immobiliser, any locksmith can cut a replacement without programming. If it has an immobiliser (most post-1998 models do), the transponder chip must still be programmed.
Remote Keys and Flip Keys
The most common type on modern Vauxhalls. The key fob has two or three buttons for central locking, and the blade either slides out (flip key) or is fixed. Both the remote function and the immobiliser transponder chip need to be synchronised to the vehicle using diagnostic software.
The Astra H uses a flip-style key where the remote and transponder are programmed at the same time. The Corsa D and E also use flip or remote blade keys. Spare or replacement keys for these models cannot be bought second-hand and re-programmed - the transponder chip can only be coded once, so a fresh blank is always required.
Keyless Entry Proximity Fobs
Used on later Vauxhall models including the Insignia (from 2008 onwards) and newer Corsa and Astra variants. The fob communicates via RFID; the car unlocks when the fob is nearby, and the engine starts via a push button. Proximity fobs are the most expensive key type to replace due to the advanced programming required.
Vauxhall Key Costs by Model - Price Comparison Table
| Model | Key Type | Auto Locksmith (approx.) | Main Dealer (approx.) |
|---|---|---|---|
| Corsa B/C (pre-2006) | Non-remote / basic transponder | £55-£90 | £100-£180 |
| Corsa D/E (2006-2019) | Remote / flip key | £90-£160 | £200-£310 |
| Corsa F (2019 onwards, Stellantis) | Remote / keyless | £110-£180 | £250-£400 |
| Astra G (1998-2004) | Non-remote transponder | £60-£100 | £120-£200 |
| Astra H (2004-2009) | Flip remote key | £90-£160 | £200-£300 |
| Astra J/K (2009-2021) | Remote / flip key | £100-£170 | £220-£350 |
| Astra L (2021 onwards, Stellantis) | Remote / keyless | £130-£220 | £300-£450 |
| Insignia A/B (2008-2022) | Proximity fob | £130-£200 | £300-£450 |
| Mokka B, Grandland (Stellantis) | Remote / keyless | £130-£220 | £300-£450 |
Prices are approximate UK market ranges including cutting and programming (ex VAT), gathered from published locksmith and dealer quotes rather than any manufacturer price list. Exact costs depend on year, trim, supplier and whether any working key survives. The Insignia was discontinued in 2022; Vauxhall has been part of Stellantis since the group was formed in 2021, and the newer models share PSA-derived electronics rather than the older GM architecture.
Where to Get a Vauxhall Replacement Key
Vauxhall Main Dealer
A Vauxhall retailer will supply a genuine OEM key. You will need to provide proof of ownership, your driving licence, the vehicle VIN, and in some cases your Security Car Pass - the credit-card-sized card in the service folder that carries the VIN, key number and security code. If you do not have it, the dealer must order a replacement from Vauxhall, which takes several days and adds to the cost. One limitation to know: the Car Pass records the car as it left the factory, so if the immobiliser or a control module has been replaced during the car’s life, the card’s code will not work.
Typical dealer cost: £200-£450 all-in (key, programming, and VAT).
The dealer route makes sense if your car is still under warranty, or if you want a fully manufacturer-backed replacement with a service record. Otherwise, it is rarely the fastest or cheapest option.
Independent Auto Locksmith
A qualified auto locksmith can supply, cut, and programme a Vauxhall replacement key at your home or roadside, usually on the same day - including emergencies. On GM-era cars the locksmith reads the security PIN from the vehicle through the OBD port, so there is no need for a Security Car Pass or a tow truck. On Stellantis-era cars the position is different (see below), so say which model and year you have when you call.
Auto locksmiths are typically 30-50% cheaper than a Vauxhall dealer and come to you.
City Locksmith London provides mobile Vauxhall key replacement across Greater London - car key programming from £85, key duplication from £109 (ex VAT), with no call-out fee and free quotes.

Online Key Suppliers
Online services can supply a cut-to-code blank at a lower upfront price, but they cannot programme the key remotely. You still need a locksmith or dealer with the right equipment to programme the transponder and sync the remote. This two-step process rarely saves money once labour is added, and it is not a useful option if you are locked out.
What Happens When You Lose All Your Vauxhall Keys?
Losing every key is more serious because the vehicle’s immobiliser must be reprogrammed from scratch. A Vauxhall dealer will typically ask for your Security Car Pass. If you do not have it, they charge for ordering a replacement PIN and the wait is often several days.
A specialist auto locksmith can resolve this without the Security Car Pass:
- The locksmith connects a diagnostic laptop to the OBD port and reads the PIN code directly from the immobiliser module memory.
- On older models where OBD access is not possible, the immobiliser EEPROM chip is read directly.
- A new blank key is cut and programmed on-site using the extracted code.
- The locksmith tests the new key and, if required, deletes any lost or stolen keys from the vehicle’s memory so they can no longer be used.
The whole process typically takes under an hour on GM-era Vauxhalls.
The Stellantis-era exception (Corsa F, Astra L, Mokka B, Grandland)
The newer models do not work this way. They use PSA-derived electronics with a security gateway, and the immobiliser code is held on the manufacturer’s servers rather than being readable from the car. That means an all-keys-lost job on these generations needs manufacturer-level diagnostic access and a time-limited code obtained per job, which not every mobile locksmith holds.
The practical consequences for you:
- Adding a spare while you still have a working key is straightforward and quick on all generations.
- All-keys-lost is a different booking, takes longer, and costs more on Stellantis-era cars.
- Ask directly: “can you do all keys lost on a 2023 Astra?” A locksmith who cannot will say so, and a locksmith who asks for your registration and VIN first is doing the job properly.
This is the single strongest argument for getting a spare cut before you need one.
How Is a Vauxhall Key Programmed?
OBD Programming (Most Modern Vauxhalls)
The locksmith connects specialist diagnostic software to the car’s OBD-II port. The software communicates with the BCM (Body Control Module) or CIM (Column Integration Module), reads the immobiliser data, and writes the new key’s transponder chip to the vehicle’s allowed key list. The remote locking function is synchronised at the same time.
EEPROM Programming (Older Models)
Where OBD programming is not supported, the locksmith removes the immobiliser module and reads the EEPROM chip directly using a programmer device. This extracts the cryptographic seed needed to generate a working transponder code for the replacement key.
CIM Faults on Vauxhall Corsa and Astra
The CIM (Column Integration Module) on Corsa D/E and Astra H models is a known failure point. It controls the immobiliser, steering wheel controls, and ignition communication. A faulty CIM can prevent key programming and may need repair or replacement before a new key can be made. A qualified auto locksmith can diagnose a CIM fault with the same diagnostic equipment.
Programming Requirements by Key Type
| Key Type | Programming Required? | Who Can Programme It? |
|---|---|---|
| Non-remote (no immobiliser) | No | Any locksmith or key-cutting service |
| Non-remote (with immobiliser) | Yes | Auto locksmith or dealership |
| Remote / flip key | Yes | Auto locksmith or dealership |
| Keyless proximity fob | Yes | Specialist auto locksmith or dealership |
Common Vauxhall Key Problems and Fixes
Key won’t turn in the ignition - Often caused by a locked steering column. Try gently turning the steering wheel left and right while turning the key. If the issue persists, the key blade may be worn and the cut profile no longer matches the barrel precisely.
Remote stops locking/unlocking the car - The most common cause is a flat battery in the fob. Most Vauxhall remote keys use a CR2032 coin cell, available for under £2 at any supermarket. If a battery swap does not fix it, the remote may need re-synchronising.
Keyless fob not recognised - Can be caused by a flat battery, radio frequency interference, or the fob falling out of sync with the vehicle. A locksmith can re-synchronise the fob using diagnostic software in minutes.
Key blade snaps in the ignition - Common on older Corsa and Astra models, particularly with worn flip keys. A locksmith can extract the broken blade, inspect the barrel, and supply a new key. Do not try to extract a snapped blade with pliers as this can damage the barrel.
Lost or stolen key still a security risk - An auto locksmith can delete the missing key from the car’s immobiliser memory, rendering it permanently unable to start the engine.
How to Save Money on a Vauxhall Replacement Key
- Get a spare before you lose the original - having a second key cut and programmed while you still have the first is significantly cheaper than an emergency replacement later, and on a Stellantis-era Corsa F or Astra L it is the difference between a routine visit and a manufacturer-level job.
- Compare quotes - an auto locksmith is almost always cheaper than a dealer; see our locksmith price list for typical London rates.
- Check your insurance - some comprehensive motor policies include cover for lost or stolen keys; check your policy documents before paying out of pocket.
- Avoid second-hand keys from eBay or scrap yards - Vauxhall transponder chips can only be programmed once and are locked permanently after coding; a used key from another car cannot be reprogrammed to yours.
- Ask for a VAT receipt - any reputable locksmith will provide one as standard.
