My keyless entry for my 2008 Volvo s 40 won't work. I've tried replacing the battery but it still doesn't work. Anything I may can do before spending money on a new key.?
How are you trying to open the door , button on key fob ? With this system you can pull up on the drivers handle an it activates
Antennas in the external side door handles (C30/C70 front doors, S40/V50 rear doors)
Antennas in the passenger compartment and cargo compartment
An antenna in the rear bumper
Quick lock motors in the lock units in the side doors
The remote keyless entry (RKE) receiver receives a signal from the key
The switch in the clutch pedal (manual transmissions) or a signal from the brake pedal switch via the central electronic module (CEM) (automatic transmissions)
Switch in door handle and lock button on handle .
If a door handle is pulled outward, a switch closes that wakes up the system and activates the antennas in the handles on the side where the handle has been pulled out. If a valid key is within a radius of approx. 1.5 metres from the handle, the relevant door will open and the vehicle will unlock one or several doors. Which doors are unlocked depends on the settings for the system. The vehicle can also be unlocked if the handle is affected on the tailgate.
