Valet key will not start volvo s80. turns in

Try turning the steering wheel while trying to turn key. It may take some force on the wheel, but don't turn the key hard!

However this has nothing to do with your start problem. Check all interlocks (shifter park vs neutral), Key Switch, etc.

Hold down the odometer reset button, turn the ignition key to position 1 for 1-2 sec. Then, turn the key to position 2 still holding the button down. Wait for the service light to flash and release the button. It can be tricky. It may take a few times to get it.

try your spare key, the one you are using may be worn out.

having the same problem with my 1999 s80 2.9 . replaced the abs module twice and still get the brake failure warning. when the ignition key is turned there is a clicking sound from the center console beneath the shifter, then the brake failure warning, and the car will not start. (also after the last abs module replacement the car sometimes gets stuck in park).

Pay the dealer the $300.00. I have been told it's worth it to have an extra set due to the computer communication of the keys with the ignition (not sure how it works exactly.) To re-key or get a new ignition costs like 1600-1800 dollars and takes approximately 10 days to even get the parts. I checked with a Volvo dealership in WA State. I am having problems with my ignition now and the keys won't come out or turn the last little click to be able to pull them out (but not all the time), also my car will turn on no problem (only have trouble getting keys out) my car just won'y go into gear, it seems it happens more frequently when it is below 55 degrees, even after the car temp guage has reached the half way mark. I have a 1999 Volvo S80 (I hate that car!)

 I had same problem put the key in the other way it worked for me , suggested by my breakdown truck guy.

V50 2005 and similar year have this problem.

The ignition key has two parts:
- remote control (with battery)
- RFID identification (without battery)

Car has two separate locks.
The upper lock is where you put the key inside and turn to ignite.
The lower lock is right at the steering wheel which electronically locks the wheel.

The "upper lock" sometimes refuses to recognize the key. It might be a bad contact or bad mechanical placement. Typical problem for this car.
Try hitting the dashboard and the lock with your fist few times (not too much!). If there was only a bad contact, the car may start a few times.

If you have dropped the ignition key from 1m of height (or higher) to the concrete, the RFID module inside may not have survived. Try with spare key.

If nothing helps, take the car to the volvo shop to change the upper lock. That was my case...
The lock looks like this:

THE key code is what you need or a dealer should be able to give you a MASTER-KEY with the vin# and key code is on a little black tab in the owners manul package i hope this helps

Check fuel pump is working when ignition put on to position 2. Check key transponder. Hope this helps
