Your original probably had Briggs and Stratton on it but the one shown doesn't have enough wear for a 68 year old key.

Same number for the same truck.

How would anyone know if it is an ignition key, a door lock key, or a glove box lock key? Wouldn't they all be the same pattern, if made for matching locks? Weren't the original locks matching (same keys)? | | | | | Joined: Jun 2009 Posts: 787 'Bolter | | 'Bolter Joined: Jun 2009 Posts: 787 | These ignition keys have the same cut pattern, yet the blanks are different.

The key I have for my ignition has the groves on the right side.

The hex head B10 was used for the ignition & doors. The round head B11 was used as the trunk & glove box key on cars. I don't know if the B11 was used on the trucks. B10 & B11 blanks.

It operates the ignition and both doors. My glove box has no key slot. | | | | | Joined: Apr 2005 Posts: 7,440 Bolter | | Bolter Joined: Apr 2005 Posts: 7,440 | I seem to recall from my days of making keys (40+ years ago) that there were several Briggs & Stratton key blanks that had roughly the same grooves cut in them. If we were out of the correct (according to the book) blank we would just grab a different but compatible blank and cut the key. Customer didn't care just as long as the key worked. A little polishing with the wire wheel or a slight grind here or there with the cutter and all was well.

I just brought home a 55 first series C3100 and only got one set of keys. Everywhere I went ( hardware stores, Big Box) - they all said they do not have a blank, and don't think they can get one -
Anyplace you can recommend to get a blank would be appreciated
thanks

I don't remember myself. Mike B has a good suggestion. Reread post a few back, seems like trucks used B10 blanks.

And you should not have any trouble finding them locally. Are you sure you have an original ignition switch? | | | | | Joined: Nov 2001 Posts: 1,517 'Bolter | | 'Bolter Joined: Nov 2001 Posts: 1,517 | 1933 - 1966 used that blank for ignition. The b-11 is for trunks, etc. ACE Hardware,,Orchard Supply,,Home Depot. I get all my bulk blanks from www.ekeys.com and make copies of my master key set. | | | | | Joined: Dec 2015 Posts: 56 Wrench Fetcher | | Wrench Fetcher Joined: Dec 2015 Posts: 56 | Hi All thanks for the good advise, and to your question Cletis, I am not 100% certain I have an original ignition switch, but the one key I have looks much like to B10 blanks I see
How would I check for original switch on this truck?
