The quick answer
The cost depends on the exact vehicle, key system, whether a working key remains and the work required at the vehicle. Our catalogue shows listed spare-key options. Confirm the full price for your registration and postcode before booking.
1. Match the price to the job
A working key that needs a spare is a different starting point from a locked vehicle with every key missing. A damaged remote may need assessment before repair or replacement can be priced. Describe the situation before choosing an option.
Our product pages identify year ranges and key styles. Those options are a useful starting point for a spare-key enquiry. They do not automatically include vehicle entry, lost-key security changes or diagnosis of an unrelated starting fault.
- A working key remains: ask for a spare-key quote.
- Every key is missing: explain access and security needs.
- A key is damaged: describe what still works.
- A key was bought elsewhere: confirm suitability before paying for programming.
2. Understand what changes the price
The key’s functions and the work needed to match it to the vehicle matter more than its appearance. A blade, remote and proximity key are different products. Programming requirements, parts availability and any existing fault also affect the proposed work.
A newer or luxury vehicle can have more involved requirements, but its badge alone is not a reliable price calculator. Likewise, a chip key has no single universal replacement price. Use the exact model, year and registration to check the appropriate option.
- Key supply, blade cutting and required programming
- Access to a locked vehicle, if needed
- Fault diagnosis or damaged-lock work
- Call-out location, timing and any agreed additional charges
3. Compare a mobile visit with other options
Ask each provider for the same key functions and the same job scope. A low headline price may describe only a shell, blank blade or initial call-out. Confirm whether testing with the vehicle, VAT where applicable and any follow-up arrangements are included.
Mobile attendance is not automatically more expensive or cheaper than a dealer appointment. Compare the complete quote, any need to move the vehicle, parts availability and the expected completion time. For our London, Surrey, Slough and Reading coverage, give the full postcode so attendance can be confirmed.
- What is the total for my vehicle and situation?
- Which functions will the supplied key provide?
- What is excluded from that total?
- Will you obtain my agreement before additional work?
4. Request a useful vehicle-specific quote
Choose your vehicle in the catalogue, then send the registration, postcode and whether a working key remains. If the listed year or key does not match, ask us to check rather than choosing the nearest option.
For an urgent problem, call to confirm availability. Keep the agreed scope and price with your appointment details. If assessment changes the proposed repair, ask for an explanation and a revised total before authorising it.
Common questions
How much does programming a car fob cost?
It depends on the vehicle, the key’s suitability and whether programming is part of supplying a new key or a separate assessment. Ask for the complete price, including any required cutting and testing.
Are remote keys more expensive than traditional keys?
A remote or smart key can involve electronics and matching work beyond a plain blade. Compare the correct products for your car; a cheaper blade-only key may not provide the starting or remote functions you need.
Does a London postcode mean a fixed surcharge?
Do not assume a fixed regional surcharge. Give the exact location and timing, and ask whether attendance is included in the quote.
How do I find an affordable replacement?
Compare complete quotes for the same vehicle and key functions. Check whether a repair is appropriate, whether a working spare changes the job and whether your policy provides relevant cover. A low headline price alone does not establish the final cost.
