My original ignition lock cylinder is pretty loose and by what I mean by that is the key is loose inside the cylinder and you have to hold the key for the key buzzer to work. I worry sometimes that loose fit may cause an issue.

I ordered a new cylinder and the key is much tighter in the cylinder. The key buzzer works like it is suppose to with out holding the key and as you start the car the key just feels like it has more contact with the tumblers.

Since the original cylinder has the correct code that is listed on my bill of sale, I would like to keep it. Can these be rebuilt so the the key fits tighter? Has any one had one rebuilt? I was thinking about running by a lock smith on the way home to talk to someone about it.

The can recode your new lock with the original code. Your old key and cylinder are probablty just worn out. New ones with old code should be fine.
Note: key codes are marked on lock cylinders (think it is RH front door cylinder); just in case you do not have the original key code.

I was more interested if the old cylinder could be rebuilt since the code is on the cylinder. It would be nice to keep the old one with the car since it matches my bill history.

From what I remember, the RH front door cylinder is the only one stamped with a code.

My ignition cylinder has it on the side.

It depends. If you're lucky then the pins are worn that makes the key feel loose. Any decent locksmith can repin to the original combination.

I took my old ignition cylinder and a new cylinder to a local lock smith. He ended up cutting a new master key from code that really helped the key staying in to activate the key buzzer. He also recoded the new ignition cylinder to the old key. Now I can use either one and I may just use the new one and put up the old one so it does not wear any more.

Do you still have the original Briggs and Stratton keys Harold?

I don't know if they were the original but I do have a very old set that wore pretty thin. I don't think it has a C on the ignition but it could be wore off.

I have some repops of those key made as well.

This is the one I got with the car.

yup, those are the briggs and stratton type keys
