My cadilliac sts 2005 key fob started no working. when I try to start it the car tells me that the key fob is not detected. I just changed the battery and it is still doing it. What else could be wrong with it:
Open your door with key, then open middle console and there is a lil square (key fob size) put the key fob in it and then hit the ignition button and it should start............I read this somewhere and it saved my life.......also for battery in key fob, I went to lock and key place and they have a battery tester and told me the # battery I needed and bought key fob battery from pharmacy (energizer) for $1.49
hopefully this helps, also forgot to mention mine is a 2005! dk if this would matter or not!!
replacement fob i was told between $135 and $150 usd.
you can order one online cheaper. I just did and it was around $50.

Some late model fobs contain electronics beyond the push buttons.
Batteries are replaceable...small screws may let you do this.
If the battery is not the cause....a replacement fob may be expensive. A road service technician can probably troubleshoot and replace cheaper than dealer !
Thanks Kimberly 3184 u r a lifesaver that answer actually works thanks??
Mine is doing this too--saying "no key fob detected."
How do you check the fob battery to know if this is the problem? My car (purchased used) has multiple electronics issues and I'm wondering if it's a fob battery issue or related to other nuisance electrical bugs I've got going on. (Hood ajar warning when it ISN'T ajar; check theft system; check stability system, etc...) I can't lock the car or the alarm goes off thinking there was a theft attempt.

Check the fob battery you might need to replace it, The battery only has about a 3 year life
