The quick answer
A spare-key appointment adds a usable key while one still works. An all-keys-lost job starts without a working key and may also require vehicle access and security decisions. Both depend on the exact vehicle, key system and available options.
1. If one key still works
Ask about a spare and explain which functions you want: manual access, remote buttons and keyless starting are not interchangeable. Have all current keys available so the technician can confirm the relevant functions during the appointment.
A second working key can help another driver or provide a backup if your everyday key is misplaced. Store it separately and check it occasionally using the manufacturer’s guidance. Keeping both together does not protect you from losing the pair.
2. If no usable key remains
Tell us whether the vehicle is locked, whether any damaged or old keys remain and whether you suspect theft. We offer replacement-key enquiries for many vehicles without the original, but the model, year and security system must be checked first.
An all-keys-lost job can include more than creating a blade. Ask about the supplied key, programming, vehicle entry where required and any available changes to the missing key’s access. Electronic deletion does not necessarily stop a separate mechanical blade from operating a lock.
- Vehicle registration, make, model and year
- Exact location and whether the vehicle is accessible
- Any working, damaged or old keys still available
- Whether the keys were misplaced, stolen or locked inside
3. Understand what duplication means
Copying a blade shape does not establish that an electronic key will start the car. Depending on the vehicle and the intended product, electronic matching or programming may also be needed. A similar-looking fob is not evidence of compatibility.
A mobile appointment can be suitable for spare and replacement work, subject to the vehicle and location. The catalogue’s listed spare-key options help you identify a potential match; the team checks the actual registration and job before confirming it.
4. Check the result and keep a backup plan
Before completion, ask which keys remain usable and test the agreed functions with the technician. Keep the invoice and any care instructions. For a replacement after theft, discuss both electronic and mechanical security rather than assuming one change addresses every route of access.
A spare is a practical backup, but it does not guarantee an insurance discount or eliminate every lockout. Keep an agreed storage routine and a way to contact a trusted person who can safely bring the spare if needed.
Common questions
Can a car remote be duplicated?
Suitable replacement remotes can be supplied and matched for many vehicles. The exact model, year, key specification and available equipment determine support. Copying the casing or blade alone is not enough.
Do I need the original key to get a replacement?
Not for every vehicle. Tell us if no working key remains so we can check the appropriate replacement process and quote. Do not book it as a routine spare without explaining that detail.
Who can duplicate an advanced smart key?
Choose a provider who confirms support for your exact vehicle and key system, explains the supplied functions and tests them with the car. A general key-cutting service may not cover that electronic work.
Where can I arrange a spare near me?
Browse your model, then contact our mobile team with the registration and full postcode. We cover London, Surrey, Slough, Reading and surrounding areas subject to appointment confirmation.
