we have a 2010 S80 with the rectangle key that fits in the dash. It wouldn't release about 6 months ago, it eventually released and we took it to a mechanic that check the computer that showed "no event" also it stuck with both keys and eventually released. It stuck again two days ago. My mechanic has tried disconnecting the battery,, no luck,, giving the battery a surge , still no luck,,, tried putting pressure on the gear shift in park, still no luck,,, any suggestions would be greatly appreciated

 

Mechanic had it again,,, and boosted the power from the battery and the ignition released the key, checked system for a short in system, negative short. Checked battery and battery failed. Purchased battery less than 1 yr ago from Sears. The battery never acted as if it was low voltage/amperage, car always started fine and no indications on the instrument panel of any problems. Put in the Volvo recommended battery and seems to work fine. Mechanic works on Volvo/BMW and Mercedes,, we don't have a Volvo dealership nearby. Mechanic said he'd never seen this problem before.

 

Hi dodgerkcj,

Will give further details, how the system is short and from where?

 

did you find out what was the problem?? i am experiencing the same issue but i have charged the battery and also put a booster to it and no luck.

 

I seriously doubt that it is a battery or voltage issue. If you can insert the key and start the car, that shouldn't have anything to do with the key release. I would instead be changing the key holder.

 

I doubt it to but im turning to the forum to see if anyone has lead to where should i tackle the issue. Any ideas??
I read on another port the relay for the start which one is that i know there are some relays on engine bay there are 3 2 square one and 1 rectangular do anyone know where is the description of these
