Key Fob? As in FOBIK Key system? What year is your Vehicle and what Key system do you have?I just had the recall performed on a Commander I just bought. I can't tell any difference in turning the key. I would say the new key fobs are great because the ones that came with the vehicle were almost useless from wear. Go back to dealer and see if it is installed correctly. Something is wrong if your wrist is sore.
Yes, from my understanding, the Transponder Key uses a regular lock cylinder connected to the ignition switch in addition to a transponder chip in the key, that regardless of the key blade being able to turn the lock cylinder, the vehicle will NOT start if it doesn't identify the Transponder Chip as being one that is accepted.Got mine done yesturday and no I didn't get a new key they replaced the silinder and then they have a lock smith match the pins so you can use your own key not new key. It is a little hard but nothing to extreme for me just have to push and twist off. I also had the P74 recall for the drive train reflash everything went well but I was told that sometimes it doesn't work and the customer has to go back the next day and they had a customer that it took 3 days to get the correct update for her jeep to start working fine again if it screws up the jeep won't drive. They also told me there were 3 updates for my jeeps software but those would cost $55 so I didn't get those.
If the issue is the key being accidentally switch to off, that would revolve around the lock cylinder itself. I'm pretty sure the Commander does NOT have the ignition switch integral with the lock cylinder. The switch fits to the lock cylinder. So all those folks with transponder keys ('06-'07?)thinking their ignition switch electrical problems is covered under the recall may be in for a big surprised when they find out the actual "switch" isn't changed, just the parts dealing with turning the key, and they have to replace the bad part or repair the electrical problem in their vehicle.
The FOBIK key system ('08 and up?) works totally differently, so the entire ignition switch module is replaced.
You would have to rekey the lock cylinder to work with the existing key or rekey the door locks for the new keys. There are plenty of replacement ignition switches that are different than OEM from the factory in that they are easy to rekey in order to key them to the existing key for the vehicle. You really don't have to be a lock smith to key these, its so simple many guys at the Dealer Parts Counter know how to do it for the customers that order them.
I can also see Dealers being lazy and instead of rekeying the new lock cylinders for existing keys or changing the door cylinders for new keys, they simply swap the new lock cylinder in, hand the owner the new keys and expect them to live with two different keys for their vehicle, the old ones for the doors and the new one for the ignition. Since the key head has a remote, it might be a long while before the owner realizes the new key will NOT unlock the doors if the remote is NOT working.
Now the Fobik's, I am almost positive that replacing just the ignition switch module does NOT require new keys. People have posted they replaced those and the old keys worked just fine. So I'm puzzled why dealer would be providing new FOBIK's, but we haven't established that yet. Since the old transponder key's had a remote in the key head, we get a lot of people calling those keys FOBIK's or Key Fob's and confusing the issue.
