(T) passsenger key lock

this is my first post

i have had no problems with my key lock, untill today i have aFiat CINQUECENTO from 1993, ex condition, but i locked the doors from the passenger side the other day, as i pulled the key out it unlocked, i discovered that i had the driveer door slightly open.

now i cannot get the key into the passenger side, all other doors , no problem can anyone hel, the key goes in half and thats it,



layla

my keys have been a bit stiff . had a major temper with the fuel cap the other day. i think its just hwere it is so cold and the locks are freezing. i got some wd40 and sprayed it inside the locks. i also put a bit on the key then when the key went in wiggled it about and there all perfect now. give it a shot.

thanks, ill give it a try, my driverside and boot work, hopefully with a bit of wd it'll go

the key goes half in and then stops

any other suggestions are welcome
