dont put your phone in the same pocket as your key anyways.

1. screen could get messed up
2. could mess up transmitter

 

I was the one who had the same problem and opened the other thread. it is definitely the key. Mitsu has a TSB out on it. Just get both keys to the dealer and they should get it done for you under warranty.

 

So the moral of the story.

Owners manual owns you.

And what's wrong with the Panasonic battery? The one you would buy is most likely made by Panasonic and rebranded as redtop bla bla bla.

 

The thing that kills me is why does it matter if you have a phone on you. my wifes lex has the push start and keeps her key fob in her purse with 2 phones and she never has a problem. ???

 

Because those keys have the EMI shield that the mitsu keys SHOULD have come with. The new part apparently fixes this problem, or so says Mitsubishi.

Interesting

 

just got back from the dealer and they gave me two NEW keys according to the TSB. They said they should be better with dealing with cell phones but still to try and keep them apart. Both keys work great.

 

Yes because the problem the OP had is on the CAR MANUAL and the battery is the same whatever you choose to believe.

 

im guessing you carry your manual with you everywhere you go??

And for the record, putting the key back in the FOB is not a traditional thing to do, it should be labeled more clearly on the key and it should lock in when you put it back in there. Its a design flaw IMO.
