"Got a 2019 SEAT Arona FR. Dropped my only key down a drain on Prince Street in Driffield — proper comedy moment, I was fishing for it with a coat hanger like an absolute idiot. Water was about two feet deep, key was gone. Called Ian, he was with me in 45 minutes. Cut and programmed a brand new KESSY smart key on the spot right there on Prince Street. The keyless entry and push-button start both worked perfectly. Couldn't believe he could sort it kerbside like that."

SEAT Key FAQs
How much does a SEAT key cost?+
SEAT keys from £120 for basic non-remote keys. Remote flip keys (Leon, Ibiza, Altea) are £140-£180 including cutting and programming. KESSY smart keys (Ateca, Arona, Tarraco) cost £200-£280. All include mobile callout to your location.
Do SEAT keys use VW parts?+
Yes — SEAT is part of the VAG group alongside VW, Skoda and Audi. The transponders, remote boards, and immobiliser systems are often identical. A Leon key programmes the same way as a Golf — we do these every week.
Can you programme SEAT KESSY keys?+
Yes — KESSY is the VAG proximity key system on Ateca, Arona, Tarraco and higher-spec Leons. We supply and programme replacement KESSY smart fobs. Keyless entry and push-button start both work as expected.
How long does a SEAT key take?+
30-60 minutes for most models. IMMO3 systems (older Ibiza, Leon Mk1) are quicker. IMMO4/newer systems need a secure OBD login which takes a bit longer. We carry common VAG blanks so there's rarely any waiting for parts.
Can you help if I've lost all my SEAT keys?+
Yes — all-keys-lost recovery for all SEAT models. We gain entry, programme new keys via OBD, and delete lost keys from the immobiliser. Covers all immobiliser types. Proof of ownership (V5C) required.
Is a SEAT key cheaper than a VW key?+
SEAT keys cost about the same as equivalent VW keys — same technology, same transponders, same programming. Price depends on the immobiliser generation, not the badge. Fixed quote upfront, no hidden costs.
SEAT Key Lost or Not Working?
Leon, Ibiza, Ateca, Arona — whatever SEAT you drive, we'll get a new key programmed and working. Usually within the hour.
