I am hoping someone here cal give me an understanding of what might be going on with my 2005 GS300.
I fitted a new Enduroline 069 75AH battery in August 21 - recommended by a friend - and then a couple of weeks later moved house but in the meantime had been using the car regularly.
After moving house the car stood for a week or more without being driven and when I went to use it againa I tried to unlock the car using the fob without any success, so I tried the spare fob, and again no success.Thinking it might be the fob battery I changed it in both fobs - but still no success.
I used the key to unlock the car, and the alarm went off. The dash display had a message - no remote key found.
I closed the car and within a few minutes the alarm silenced and the car locked.
I left the car and used my wifes car and when I got home a couple of hours later I tried again. The first fob didn't work, but this time the second did. All was well for a short while until yesterday when, after having used the car a few times last week, I had exactly the same problems with neither fob unlocking the car until after numerous tries over the next 30 minutes, one of the fobs worked.
I used the car covering about 10 miles, and on my return parked the car, turned the engine off and locked the car. 2 hours later one of the fobs successfully opened and started the car again, but the second did not.
This morning, one fob opens the car but the other doesn't.
Any suggestions to resolve this would be appreciated.
(I do have another problem with an intermittent 'Check VSC warning which started about the same time, but I'll deal with that seperately)
