- Component protection handling on selected platforms
- EEPROM-level solutions for certain lost-all-keys scenarios

FAQs
Can you make a new SEAT key without the original?
Yes. We can create SEAT keys from scratch, even if you’ve lost the only key. We use key code data, locks, and specialist programming to pair a new key and remove the lost one from the immobiliser.
Will you damage my SEAT when unlocking it?
We use non-destructive entry techniques wherever possible. Drilling or replacing a lock is rare and only considered if a lock is severely damaged or tampered with; we’ll discuss options and costs first.
How long does SEAT key programming take?
Many jobs are completed in one visit, often within an hour on-site once we arrive. Times vary by model, key type (remote vs smart), and whether all keys are lost.
My SEAT says “key not detected.” What should I do?
Try a fresh fob battery and hold the key near the steering column or start button. If it still won’t start, there may be a transponder or immobiliser pairing issue. We can run OBD2 diagnostics, test your key, and reprogram or replace it as needed.
Can you erase a stolen SEAT key from the system?
Yes. We can remove stolen keys from the immobiliser so they can’t start your vehicle, then program new keys and remotes to restore full security.
Do you provide spare SEAT keys and duplicates?
Absolutely. We can supply and program spares on your driveway or workplace. Having a spare is cheaper and faster than replacing a lost last key later.
