- SEAT key won’t turn or car won’t start
- Key fob not responding or intermittent locking

SEAT Models We Support
We work with most SEAT models, including:
- SEAT Ibiza, Leon, Arona, Ateca, Tarraco
- SEAT Toledo, Altea, Alhambra, Mii
- Cupra-derived systems and newer 2024/2025 platforms
From older transponder chip keys to the latest smart/proximity keys, we carry blanks, remotes, and diagnostic software suitable for the majority of UK-market SEAT vehicles.
How Our SEAT Locksmith Service Works
- Assessment and ID checks
- We confirm vehicle ownership and assess the issue. If keys are lost or stolen, we discuss options such as deauthorising old keys.
- Non-destructive entry
- For lockouts, we use specialist picks and techniques to open your SEAT without damage wherever possible. Any exceptions are explained in advance.
- Key cutting and cloning
- We cut a new key blade (standard or laser cut) using code or lock decoding. We can duplicate a working SEAT key or create one from scratch if you have none.
- SEAT key programming
- Using dealer-level diagnostic tools via the OBD2 port, we perform transponder programming so the new key starts the car. On certain models, we use EEPROM/ECU immobiliser programming when security protocols require advanced procedures.
- Remote and smart fob setup
- We pair the remote functions (lock/unlock/boot) and configure smart/proximity keys so your push-button start works as intended.
- Testing and handover
- We verify that the car starts, locks, and unlocks correctly and provide guidance on caring for your new key. Workmanship and keys are backed by our warranty.
Common SEAT Key and Lock Problems Solved
- Lost all keys: We can create a key from scratch, program immobiliser data, and remove lost keys from the system for your peace of mind.
- Faulty remote: We test and repair or replace the remote module, including battery replacement and re-synchronisation.
- Car won’t recognise key: We diagnose immobiliser faults, antenna issues, or key transponder failures, and carry out the required reprogramming.
- Key stuck or snapped: We provide broken car key extraction from doors or ignition, then repair or replace the key and address any lock damage.
- Central locking faults: We assess door modules, actuators, and remote central locking to restore reliable operation.
If your fob has suddenly stopped working, you may find our guide useful: read about resolving a key fob not working. If you’re fully locked out, our specialist vehicle unlocking service can help.

FAQs for SEAT Keys and Locks
Can you make a SEAT car key without the original?
Yes. We can create and program a new key from scratch using your SEAT’s immobiliser data. We verify ownership and then carry out decoding, cutting, and programming on site.
My SEAT says “key not recognised” and won’t start—can you help?
We can diagnose whether the fault lies with the key’s transponder, the car’s immobiliser antenna/ECU, or a software issue. We then reprogram or replace components as needed to restore starting.
Do you offer non-destructive entry for SEAT lockouts?
Yes, wherever possible. We use specialist picks and methods designed to avoid damage. If a rare destructive method is unavoidable, we’ll explain why and obtain your approval first.
Will my new SEAT key work for both locking and starting?
Yes. We program both the immobiliser (so the car starts) and the remote functions (lock/unlock/boot). On smart keys, we also ensure proximity and push-button start operate correctly.
Is this service quicker than going to a SEAT dealer?
Typically yes. As a mobile service, we come to you, often same day, avoiding the need for towing or long dealership waits. Our diagnostics are dealer-level, and our prices are competitive.
Do you cover my part of Harrow?
