Recently purchased a 1990 toyota camry , just replaced the ignition lock cylinder (ignition switch) due to on and off starting problems (key wouldn't turn most of the time) now a week later possibly bad alternator. Car just wouldn't start. I was wondering if these could be related ?
my ignition is badly worn out needs to be replaced
I had this problem and had to eventually replace the key tumbler. It was somewhat difficult to find the pin that released the tumbler, but once it's out, the new one just slides in.
door wont open with key when locked new key like new
I have replaced the ignition key 3 times in 140,000 miles.
It just wears out. Replacement keys work without issues...for a while
