    Frank, where in MI are you? I'm in the Flint area on a fairly frequent basis ( every two months or so)

    If the link to Photobucket works, these pictures might help for '98 to '04 Sevilles.

    Remove the trim panel from the bottom of the parcel tray; where the trunk light is located. Unsnap the plastic assembly and pay attention to how it is oriented so you can install it again.

    Remove the RKE module and remove the cover of the module. The circular land at the bottom RH corner is where you want to solder a non-stranded hookup wire. Choose wire with a neutral color insulation or a color that blends with your interior.

    Feed the wire through the hole in the cover and put it all back together.

    Feed the wire into the cabin directly in front of the rear glass at the rear edge of the parcel tray. The wire length is not critical; all you are trying to do is feed the RF to the RKE module that is otherwise shielded by the car body.

    Have fun.

    Jim, excellent writeup...this could go in the Tech Tips if you do another writeup I think.

    Re: Keyless Entry RANGE

    Does anyone know where this thing is located in a 97 STS? Is it the black round thing under the back dash cover? Somtimes I can make the remote work from halfway across the parking lot. Sometimes it wont work even if im right next to the car.

    Re: Keyless Entry RANGE

    A big issue with any radio link like this is interferring signals from another source that swamp or overload the receiver. Your range problem may not be your equipment at all but the result of transmissions from other sources prevalent in an urban setting. Examples would be, automatic doors, radio and TV stations, security systems, cordless phones, baby monitors and the Lord knows what else.

    The 1997 model years use a different keyless entry module located in the trunk under the package tray. Your poblem may be bad keyfobs or corrosion/ connection in the keyfob. Have you replaced the battery?

    see the attached link for a pic of a 97 module.

    The 99STS has an antenna enhancement modification that will help the keyless range.
    See post 18 for pics, JimD was kind enough to post these pics. Thanks JimD

    Yes, in both remotes. Same thing as before.

    Re: Keyless Entry RANGE

    Could someone please re-post pics of this technique? I'm trying to follow along in my head using memory but I'm not quite tracking. Pictures always helps...something about 1000 words...

    Thanks,

    Re: Keyless Entry RANGE

    I did mine up today. What an easy job! I used an old wire wall mount FM antenna that I think came from my Panasonic all-in-one stereo system from the 1970's. After soldering the base wires to the remote receiver, I ran the two separate antenna leads up through one of the baby car seat anchor points that is behind a zipper opening at top/middle of the back seat. After running the wires across the entire seat back, I stuffed them between the rear deck and the seat so one can't see them. The result is a significant increase in the range. I was across the street at a neighbor’s house easily 100 ft away and it worked. There was also an improvement in the speed that I can program the TPMS system which was hit or miss before depending on the outside temp.
