I have 2 keys and they are both the same, they both work without a problem in the passenger door. Unfortunatly I didn't get the key fob with the car so I cant test that.
When I turn the key in the drivers door I can see the button moving slightly but no joy. It always lock it 1s try.
When starting the car its as if the keys going too far into the cylinder.
I will point out that this car appears to have had a hard life, a few scrapes and dents, cracked grille and headlight surround, passenger electric window didn't work, and the interior was disgusing. There was enough dog hair in it to create a new dog. I think the problem is general wear and tear but I'm unsure how to procede.
The cars starting to look a bit better after a full professional valet, but even they couldn't shift all the dog hair

.
I think I'm gonna start looking for a better interior but in the mean time I'm going to have to settle for seat covers.
