Your Local Seat Key Specialist
I'm Dean — a specialist mobile auto locksmith based in Honiton with over 15 years of experience, including regular work on Seat vehicles. Like Skoda, VW and Audi, Seat is part of the VAG (Volkswagen Audi Group) and uses the same progressive immobiliser generations — from the older IMMO 3 on early Ibiza and Leon models through to the newer MQB-platform IMMO 5 on the Arona, Ateca and Tarraco. Whether you've lost your Seat keys, need a spare Seat key cut and programmed, or your Seat immobiliser is showing a fault, I carry professional AUTEL and Xhorse equipment covering the full Seat range.
Unlike a main dealer, I come to you — home, workplace, car park or roadside — and complete the Seat key programming on-site. The shared VAG platform means the same diagnostic equipment covers Seat, VW, Audi and Skoda — which typically results in faster resolution and significantly lower pricing than a Seat or VW Group dealer.
Seat's Cupra sub-brand — covering the Cupra Born EV, Cupra Formentor and Cupra Leon — uses the same MQB-platform immobiliser as the standard Seat range. Key programming on Cupra models is handled identically. For advice on VAG-platform key security, Which? has a practical guide on choosing a reputable locksmith.
Seat Key Types We Work With
Seat has used a range of key and entry technologies across its model range. I work with all of them:
Seat Flip Keys
Fold-out blade keys with integrated remote, common on Ibiza and Leon.
Seat Keyless Access (Kessy)
VAG-platform proximity smart keys for push-button start on Ateca and Tarraco.
Seat Keyless Entry
Detect-and-go systems on newer Arona, Ateca and Tarraco.
Seat IMMO Transponder Keys
Chip-coded keys pairing with the VAG immobiliser generation.
Seat Smart Keys
Push-button start keys on newer MQB-platform models.
Cupra Keys
Smart keys on the Born EV, Formentor and Leon Cupra — same VAG MQB immobiliser.

Our Seat Auto Locksmith Services
Seat Key Replacement (Lost Keys)
Lost all your Seat keys? No original needed. Using your VIN and VAG immobiliser data I create a complete replacement from scratch on-site. See lost car keys.
Spare Seat Keys
A spare Seat key prevents future lockouts. I cut and programme spares for all Seat and Cupra models on-site — flip keys and Kessy smart keys.
Cupra Key Programming
Born EV, Formentor and Cupra Leon key programming uses the same VAG MQB immobiliser as standard Seat models. No additional complexity, same-day mobile service.
Seat Key Programming
Seat key programming across all VAG immobiliser generations. My AUTEL equipment programmes new keys and resolves IMMO faults on both older and newer MQB-platform Seats.
Seat Key Fob Repairs
A Seat key fob that has stopped working often just needs a battery, button repair or reprogramming. I diagnose and repair before recommending a replacement.
Seat Broken Key Extraction
Snapped a Seat key in the door or barrel? I safely extract the broken blade and cut a fresh working key on-site.
Common Seat Issues We See
Across thousands of Seat callouts, certain faults come up again and again. If you're experiencing any of these, I can help:
Recent Seat Job — Exeter
Seat Leon — Lost Only Key
A customer lost the only key to a 2018 Seat Leon in Exeter. The VAG-platform immobiliser means this is a specialist job requiring AUTEL-level diagnostic equipment. I attended the same day, gained non-destructive entry, read the IMMO module, programmed a new smart key on-site, and deleted the missing key for security. The customer was back on the road the same afternoon at well below the Seat dealer quote, no recovery vehicle required.
Main Dealer vs DB Car Keys
For most Seat key and lock jobs, a mobile specialist saves you time and money compared with a main dealer:
| Main Dealer | DB Car Keys | |
|---|---|---|
| Getting the car there | ✗Recovery often needed | ✓We come to you |
| Waiting time | ✗Days, parts ordered | ✓Same day |
| Pricing | ✗Higher | ✓Typically lower |
| Where the work happens | ✗Workshop visit | ✓Mobile, at your location |
| Availability | ✗Business hours | ✓24/7 emergency |
