Toyota Auris: Key Replaced After Water Damage to the Smart Remote
A Toyota Auris smart remote had been damaged by water, and Autobahn replaced the key. A short job, but a common one: water is one of the most frequent reasons a working fob suddenly stops.

What the record shows
The cause was known — water damage — and the answer was a replacement key rather than a repair. That is often the right call: once water has corroded a fob’s circuit board, cleaning and drying do not reliably bring it back.

The points below are general information about this kind of job. They explain the work; they are not additional details about this particular vehicle.
If a key gets wet, take the battery out straight away and let the key dry fully before trying it again. Heat such as a hairdryer or a radiator can do more damage.
If it still does not work once dry, check whether the car recognises the key at all — many Toyota smart keys can still start the car when held close to the start button — and then call with the registration.
- Remove the battery immediately.
- Dry the key naturally; avoid direct heat.
- Fit a fresh battery once completely dry.
- If it still fails, a replacement is usually needed.
