Remote / key fob programming
This remote can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new remote, so a replacement has to be set up by an automotive locksmith or a dealer.
Order the correct replacement remote below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Replacement key fob
Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.
Transponder Key
A cut metal key with a chip in the head. No buttons.
Transponder Key
Find on Amazon- OE part #
- HU66
- Chip
- PHILIPS ID 44
Photos show the OEM part for each number listed. Aftermarket replacements sold online are often slightly different in appearance — the FCC ID, not the shape, is what determines whether a fob will work with your car.
Volkswagen Phaeton key fob battery
A plain transponder (chip) key has no battery. The immobilizer chip inside is powered by the car's ignition ring whenever you turn the key, so there's nothing to replace. If your key also has lock/unlock buttons, that remote portion uses a 3V coin cell — see the remote battery steps for that.
Battery tips
- If your engine won't start but the key turns, the issue is usually a worn key or the immobilizer reading the chip — not a battery.
- A spare chip key must be cut and programmed to your car before it will start the engine.
