I have a Tuffy locking console in my jeep for locking up my pistol at work. If I forget to get it before I leave until I start driving I can pull my key out of the ignition to use the Tuffy key. I've done it a lot of times with no issue. Today I pulled it out and realized I used my S-10 key to start my Jeep today. For shits and grins I tried to start my truck with the Jeep key and it didn't work. I guess I'm going to change my ignition cylinder since it'll start with the wrong key. Just wanted to give people that enjoy this feature a heads up. I remember reading a post about someone else being able to pull the key out when running.
