    On a 452 Roadster, under the carpet near the handbrake, is a box of electrickery that looks like a relay, it's the receiver for the key/alarm. They don't like wet carpets. Could it be your car's problem? :-?

    Thank you that's a great help and I agree, the wet carpet is likely to be the cause ANd to know where the electrickery is is very useful. Appreciate you taking the time to offer advice.

    FInally! I have got a battery tester and yes the batteries are FULLY discharged. Showing a tiny amount of charge but well into red zone. Have checked a few, I kept a lot of them and they are all VERY dead.

    Batteries currently lasting 7-10 days, but this is after a new session of drying out the carpet in the passenger footwell.

    Are the battery's removed actually discharged ?
    Have you checked this ?
    Does the key work immediately without anything else once you've replaced the battery again?

    Or are you having to take to car back each time to get the car to recognise the key again ?

    The wet carpet seems to be at least part of the problem, certainly the recent spasm of central locking, which has now stopped. Garage checked the sensor you described (only found it thanks to your insturctions so thank you for that) and it was clean, dry and ok. No codes and of course the norty car was behaving!
    Took it home, plugged in a dehumidifier and am removing 250ml liquid every 2 days. Batteries lasting a bit longer and no more central locking spasms. Drove the little beast to London and back (300miles) and it ran better than it has EVER run before and was a joy to drive, park etc. So may be making a little progress! Hooray. Thanks again.
