Keyless Entry Issue

Post by RobRoy594 » Sun Aug 04, 2019 5:51 am

Appreciate some advice.... This morning very early, I approached my car with the key in my pocket and was unable to open the drivers door. No sound when door button pressed.
I used the key in the fob to open the door and all hell broke loose.... Alarm !!! Help!!!

Inside, I could not turn it off. Pressing anything I could and finally it went off. Car started as normal.

NB. Later when I stopped for petrol everything worked as normal.

Any Advice?

Only 2 things I can think of :-

Was you car parked in your usual area ie, not near any radio masts etc?

Perhaps the key battery needs changing?

Others will no doubt come up with other ideas?

Thanks AndyRen, yes parked on drive as usual. Possibly Battery as 3 years old now. But it worked later on.

I had a similar issue when my battery was getting low. They recommend changing the batteries every two years.

From the online manual :-

Battery life is about one year. Replace the battery with a new one if the KEY indicator light (green) flashes in the instrument cluster. Replacing the battery about once a year is recommended because the KEY warning light/indicator light may not illuminate or flash depending on the rate of battery depletion.
