I'm having a problem with my driver side door. Its difficult to key in and turn the key from today. The passenger side door works just fine as well as the boot. The ignition turns in smooth. Car is a 1997 TF Magna. No keyless entry system and I have only one key, no spares.
Edit: Applied Graphite powder on the key surface and then keyed in, it worked!
Now, I want to know what OZB community suggest for my alternative access option into the car. Should I get a generic keyless entry (90$) or should I make a duplicate key (100$) or should I do both (190 - 20% discount = 152$)? Note that, the car costed 1100$ but it will cost 1300$ to reset the locks from Mitsubishi dealer in case the key gets lost.
Most likely one of the plastic clips inside the door that attach the door levers to the barrel have broken. Take the door trim off and have a look.
Otherwise, just buy a new barrel and get it keyed by a locksmith.
