Does anybody know where the antenna for the security system is and if there is a way to increase its range or replace it?

I have 2 850s and 3 fobs. All fobs are programmed to both 850s. Only now the 94 isn't responding well the the remote fob. I know its not the battery as the other 850 is locking/unlocking 50 feet away and the 94 only 3 feet away doesn't want to work all the time or at any range. We have to be close and even then it can take several tries before it locks/unlocks.

So it does work at times and all three fobs have great range for the other 850 so it isn't a fob battery. So i'm thinking something might be wrong with the receiver or antenna on my 94.

But where is it and can it be replaced? Or might something else be going on?

Thanks

Ken

There are a few long articles on how to increase the antenna length:

It has happened to me twice, in two years, on very cold winter mornings at about 8:00 Am. Wagon was parked outside. Pressed remote to open the car and no response, even very near to the alarm unit. Opened the car with key, alarm triggered, starter didn't work and i couldn't turn the alarm unit off with the small key. Closed the car and left with the alanm sounding. At about 13:00 pm retuned to the vehicle, pressed the remote and "voilá", was working normally as if nothing had happened before.
I think it has something to do with the receiver unit being frequency controlled by a cristal oscillator, and with the cold, these components deviate from it's normal frequency and therefore do not receive at all.
I've not oppened the unit to check my thougt, but would be interested in hearing other opinion.

Next time when you use the key to unlock, unlick it twice. Key to the right 2 times will unlock the other doors and disable the alarm.

There is no external antenna. The antenna is integrated inside the reciever unit. The reciever is located directly to the right of the glovebox. Box has to come out to access.
