Try putting the battery in the holder the wrong way round polarity wise for one minute, and swapping it back to the correct polarity, make sure the battery surfaces are clean from any fingerprints and plastic film that might be on them.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Replaced my key battery and now the red light isn’t blinking and central locking isn’t working Is it because I need to reset the key somehow with a procedure There’s now a likely connection terminal issue in the key itself Somehow I have inserted the battery incorrectly Anyone who has the same and fixed please let me know

POST 2Original post

I'd 1st check voltages of both the battery removed and new one installed. Also- does the red fob light not work if any of the buttons are pressed? I presume you mean red light not blinking is the one on you fob and not on the dash?

POST 3 / ORIGINAL POSTEROriginal post

Thanks Alex - yes no red light blinking is on the key not dash. No red light when any key pressed. Tried numerous batteries including original which was working intermittently. It’s as if by removing the battery, I now need to re-pair the key in order for central locking / boot release to work.

POST 4Original post

Key fob light should blink regardless of anything to do with the car. Take the fob out, battery out of it and give it a good blast with the hairdryer for 20 minutes......or leave on a hot radiator for the day. Then try again.

POST 5Original post

Try putting the battery in the holder the wrong way round polarity wise for one minute, and swapping it back to the correct polarity, make sure the battery surfaces are clean from any fingerprints and plastic film that might be on them.

POST 6 / ORIGINAL POSTEROriginal post

Thanks all. I’ve just visited my local Indy. After testing battery and the key, I do need a new key sadly. I called the main dealer for a price earlier and both Porsche and Independent quote £360. My Indy can fit me in the quickest so it will be done next week.

You can get it fixed for £250. Try Boyd at www.pixelsfixed.co.uk He travels up and down the country and comes to your location to fix it.

POST 8Original post

What does the hairdryer achieve when directed at the fob internals? Does it help remake a dodgy connection?
