I recently got a 1980 Porsche 924 that has been sitting for a long time, putting the key in the cylinder lock to turn on the car but the key is not turning like its locked. Checked the steering lock but seem s its not locked, tried the key on both doors locks and the trunk but it turns (little rough). The key doesn't really look worn out. I sprayed a little WD40 and tried again but nothing. Any ideas on how to approaches or if I am missing something?

If turning the wheel while trying the key does not help, it may not be the right key. Worn out ignition switches can lean to differently-keyed ignition locks. If they key does not look worn-out enough that might mean you have a newer key and an old, worn lock and you'll need to fiddle with it a lot to get it to turn (and it might still not).

Worst case scenario, you can take title to dealership and obtain new key cut by factory for your car. That way, you can at least rule out the key as the problem.

car that old (especially a 924/944) is likely to have a different key for the ignition vs the doors.
my car has a key for ignition/hatch and a separate key for driver door...and neither work on passenger door

if you reach up under the dash you can unhook the ignition switch plug and use a screwdriver to turn the switch to "hotwire"...maybe i shouldn't post that online
