Ibiza, Leon & Arona — VW Group ID48 Crypto On Site
SEAT sits on the VW Group platform — which means every SEAT from the Ibiza to the Tarraco uses the same HU66 blade and ID48 Megamos Crypto 48 transponder system as Volkswagen and Audi. Aaron programmes SEAT keys using the Xhorse VVDI2 — the same tool used on the documented Audi A5 all-keys-lost job — with OBD PIN extraction without cluster removal on most models.
SEAT uses the same platform generations as VW: PQ25 on older Ibiza 6J, PQ35 on Leon Mk2 and Ibiza 6J facelift, and MQB on current Leon Mk4, Ibiza KJ and Arona. All generations use HU66 and ID48 — the difference is the encryption level and PIN extraction method, both of which Aaron’s VVDI2 handles via OBD.
The SEAT Alhambra shares the VW Sharan platform and uses the same HU66/ID48 system. The SEAT Mii shares the VW up! and Skoda Citigo platform — a simpler key system with standard ID46. Aaron carries HU66 blanks and confirms the exact platform from your registration before setting off.
No VAT on any SEAT job. No call-out fee. Aaron confirms your SEAT's VW Group platform and whether cluster removal is needed before setting off. It usually isn't.

“Lost my Leon keys in Barnsley. Aaron confirmed it was MQB platform, came out within 30 minutes, had the ID48 crypto sorted without touching the cluster. No VAT — brilliant.”
“Needed a spare key for my Ibiza in Sheffield. Aaron came to my driveway, VVDI2 job done in 35 minutes. No VAT, cheaper than the SEAT dealer. Would recommend.”
