Mobile VW Key Replacement in Bristol & Bath

The VW range spans city cars, hatchbacks and a big van line-up, so the key story is really three stories — the cars, the vans and the odd-one-out city cars. Knowing which yours is tells us whether it’s a quick roadside job or a dealer-level one:

The blade: HU66

• Almost every modern VW uses the HU66 internal-cut blade (newer cars use a higher-security HU66 variant), cut on a Lishi HU66. A flip key whose spring has failed is the everyday VW repair — we re-shell and transfer your electronics rather than sell a whole new coded key.

The cars: pre-MQB vs MQB

• Pre-MQB (Golf Mk5/Mk6, older Polo, older Passat): Megamos Crypto / Hitag2 (ID48), OBD-programmable at the roadside — the everyday VAG job.
• MQB (Golf Mk7 from 2013, Golf Mk8, current Polo, Tiguan, T-Roc): IMMO5 with component protection (Komponentenschutz) and Megamos AES / Hitag AES chips; a new key needs component-security data via dealer-level access, which a generic key cutter can’t do.
• Golf GTI and R: the hot Golfs almost always carry KESSY keyless-go, so they follow exactly the same all-keys-lost path as any keyless MQB car — there’s no shortcut for the sporty models.

The vans: the real cut-over

• Transporter T5 and T6, and the older Caddy: HU66 with Megamos/Hitag2 — OBD roadside jobs, just like the pre-MQB cars.
• T6.1 (2019-on) and the Caddy Mk5 (2020-on): move onto the MQB-era platform and pick up component protection like the cars — a genuinely different, dealer-level job to the T5/T6 that came before [verify against your VIN].
• Crafter: the current Crafter (2017-on) shares its underpinnings with the MAN TGE and uses its own key architecture, so it doesn’t follow the Transporter pattern — give us the reg and we’ll confirm.

The city cars and keyless

• up!: the up! sits on the older New Small Family platform for its whole life, so it keeps a simpler pre-MQB key and immobiliser — usually the most straightforward VW to key.
• KESSY: keyless-go on higher trims uses a proximity smart key; all-keys-lost needs the full security data and takes longer than adding a spare.

Note: the exact pre-MQB/MQB cut-over — especially on the vans — varies by model and build date [verify against your VIN]. Give us your registration and we’ll confirm the key type, chip and whether it’s a roadside or dealer-level job before we travel — no fabricated prices.
