04 CS and funky acting ignition keys... any ideas?


Recommended Posts

Hey folks, I have some weird stuff going on with my keys.... brief summary

My 1 1/2r. old son decided to play hide and seek with my keys that contain the key FOB I usually use so I had to use the beat up key that I've had in a jar "just in case" It hasn't worked to remotely open the doors in forever but would start the car no problem. After about a week or two of using the "old" key I found my keys in my daughter's play kitchen microwave... go figure. banghead.gif

BTW around the time I "lost" my keys, the battery under my seat started giving me trouble and has since been replaced. Every time I started the car the clock reset, ac/heater wouldn't work for several minutes, along with other general weirdness

FOB #2, which has been the one that I use (since it will remotely open the doors with no problem) has stopped working in the ignition. When I insert the key nothing happens. NO dings, NO light, big NADA. and after a few seconds I get "immobilizer active" on the screen.

If I remove that key and use the other one, upon insertion I get all kinds of normal fun stuff. Dash comes alive and after a foot on the brake cranks right up. what gives?
