Hello
My wife took my 2006 volvo s40 down to the store today and she locked the doors with the key, she couldn't unlock the door with the key. so she used the optional key inside the key to open the door. thought that the battery just went dead, but no my key wont unlock or do anything for that matter. both of our keys wont do anything except start the car. is there a simple fix.... only had the car three days and this sucks... any help would be nice

Have you replaced the battery in the key fob? It's a simple watch battery.

 

i Checked the battery and it had the correct voltage but the shop checked the key fob with a RF signal tester and it showed a weak signal. So I put a new battery in it and it worked fine. weird that both would do it the same day... oh well just glad it fixed it..
