2005 s40
 

My 05 s40 won't start or release key. Have power .can hear clicking won't crank

I’m having same issue
 

B4 It would start and then stalls out but not before the gauges went haywire! I’m still having this issue

The starter solenoid is sticking so will need to be replaced , is a manual ? try push starting it

If you have an automatic, check the shifter release button to see if its stuck inward - the shifter has an interlock which keeps the car from starting when it senses its not in park and will not allow the key to be removed.

I am confused
 

I do have an automatic but I don’t know where to locate the shift realest button ? Is that on the shifter knob ? If so then no it’s no stuck?

Dondo3, if your car starts (or even tries to start), your interlock is fine.

update!! I just tried starting up this morning and it did not crank or start !! Now my key is stuck in ignition

You may simply have a weak/bad/almost dead battery or a poor connection to the ok battery.

as I stated above I have a battery jumpstart that reads off the battery voltage for me . With car off battery reads 12.4 any other possibilities
thanks in advance

Yes, a broken connection inside the battery. The battery is 6 cells connected by buss bars - metal connections between the cells connecting them in series. If one of those cracks maybe from thermal expansion and contraction the battery can still register 12.4 volts - but it won't be able to provide any current under load. Can you jump start the car? (using quality jumper cables)

A good next step would be to load test the battery and if ok - use a compatible scan tool to look for any electronic faults.

I see interesting. This morning I went to start the car and nothing now my key fob is stuck in ignition

Hoonk is right (as usual). Throw a voltmeter on the battery and see what happens when you turn the key to the start position (don't rely on the jumper box voltmeter - it could be reading its internal battery).
