Car remote keys won't open the car

You didn't use a battery saver
did you?

You will need to have the security system control module scanned to see why it is being falsely signaled to lock out the engine. Most likely the key sensor or the key has failed, try a spare key if you have one, also replace the battery in the remote if you never have just to be sure.

Check turbo waste gate

check HEAD LIGHT SWITCH
hope this work

now all you need to do is use the key to lock the doors manually and then remove it, after that use the remote to lock and open it like before.

hope it works

On the 996 and 997 there is a panel on the drivers side footwell that has a fuse panel and exposes a red positive terminal that pulls out slightly. You can connect the positive lead from a battery or charger to this terminal and the negative lead to a convenient ground spot like the door catch.

I removed the battery for the winter from my 996 and went through this process in the Spring when I realized my mistake.

you need to pull the C3 fuse and insert a wire and then put the fuse back in.
connect the neg ground to the metal steering column and the positive to the wire. close the car door and turn the door key on and off three times. open the door and now the hood latch will work.

Well, you can sometime catch the code again. Pt the key in the ignition and turn till the dash light come on (dont Start) then press and the Lock button while keeping the Lock button Pressed and turn the dash light off and put the key with the lock button Press for 10 second afterwards. If not successful first time try again. This should do it.

your ignition switch has gone bad... it will need replacing... there is an identical part made by AUdi that is much cheaper as well... tell your mechanic you would like it instead of the Porsche OEM one
