2001 Volvo C70 convertible - Remote Controls Stopped Working after flat battery

Post by Anvar » Sat Mar 02, 2019 9:56 am

Hi guys,

Recently, my car battery died and I had to call AA. After the battery replacement, both of my remote controls stopped working and it looks like the alarm is not working either as the LED light for the alarm is not lighting up at all.

So far I have researched the problem online and done the following:

1 - Changed the batteries on both of the remote controls (CR2016 3v)
2 - Checked the fuse box on the bonnet. Fuses for alarm, remote control and central locking are all fine.
3 - Disconnected the car battery for a few minutes and reconnected it.
4 - Followed the instructions from this post. https://itstillruns.com/volvo-keyless-e ... 52333.html
5 - Tried to lock/unlock the car while pressing the lock/unlock buttons(separately) on the remote control.

Any suggestions?

Many thanks in advance!

Get a full charge into the batttery, a good 10 amp,charger for a 24 hour period

Then

Lock and unlock the doors with the key in the,driver door a series of five times.

Thanks, buddy! Recharged the battery, locked and unlocked the door from the driver side 5 times, tried the procedure several times with no luck.
