this wouldn't work if you live in a city ,but we live in the extreme boonies where people rarely lock there houses. Also we never go to the "big" city at night(Eugene Oregon).So when my ignition key started getting baulky I removed the tumbler unit ,took it apart and took all the tumblers and tiny springs out then put the unit back in sans tumblers .I then put a few drops of super glue on the key and inserted it . ( the super glue keeps the key from vibrating out while driving as there are no tumblers to hold it in ,and it would be embarassing to have steering wheel lock while underway, actualy had that happen in a 240 z Datsun ,was going slow on srtaight road)I can still lock the doors trunk and fuel door and will never loose my ignition key and it turns smooth as silk......
