Göran W Posted May 21, 2011 Report Share Posted May 21, 2011 Guess I wasn´t clear..... My FOB works BUT I allways must press 3-4 times and I must be within 10 feet from the car, preferably closer! Locking works most of the time and so does the trunk. Still only at close range. Link to comment Share on other sites More sharing options...
rockfangd Posted May 21, 2011 Author Report Share Posted May 21, 2011 well I looked today and I couldnt find anything from inside the trunk. I looked on my 96 Deville. I took 2 pics and will upload tonight GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...

rockfangd Posted May 22, 2011 Author Report Share Posted May 22, 2011 here are 3 pics of the trunk compartment on my 96 Deville, The red wire is the supply for the 12 disc changer, located near the fuse panel GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Cadillac Jim Posted May 22, 2011 Report Share Posted May 22, 2011 Here's the electronics behind the back seat from my 1997 FSM page 8A-201-41. Note that the view is from inside the car, with the seat back removed. I think that there is a panel between these electronics and the trunk compartment, except for panels for access to the fuses and relays. You must remove the rear seat back to get this view. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

rockfangd Posted May 22, 2011 Author Report Share Posted May 22, 2011 so you are saying the antenna is in the V behind the seat,but is not accessable by the trunk? Why must the studs be so long that hold the rear seat back on lol. I have to use a wrench till I can fit a deep 10mm socket GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Göran W Posted May 22, 2011 Report Share Posted May 22, 2011 I doubdt that the antenna is curled. Mine doesn´t seem to be any longer than what is seen on pics. If there is more it is doubbled inside insulation. Link to comment Share on other sites More sharing options...
Cadillac Jim Posted May 22, 2011 Report Share Posted May 22, 2011 Try rearranging the antenna and walking around behind the car and seeing how far the fob works each time you move the antenna. If nothing seems to increase the signal strength, get a length of wire about four times the length of the existing antenna wire, with thin insulation (plastic or lacquer electrical or magnet wire, not a piece of an old extension cord) and tape it alongside the existing antenna wire, and use this as an extended antenna. You don't need to cut or splice wires or make electrical contact to get the extended antenna; the signal will cross over if the wires are together. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

rockfangd Posted May 22, 2011 Author Report Share Posted May 22, 2011 but the problem is that I cannot find the antenna to start with. GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
rockfangd Posted June 19, 2011 Author Report Share Posted June 19, 2011 update, am still not able to locate an antenna. IS there not one on the 96-97? GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
mike5514 Posted June 19, 2011 Report Share Posted June 19, 2011 To reprogram the fobs, while in Diagnostic mode go to RFA then RFA override then fob 1 use warmer to go to 99 Hold trunk button and press Lock button within 1 second and hold both buttons for 10 seconds, door locks will cycle, go to key fob 2 and repeat. Must do both fobs at same time. Any doubts stop! Mike Link to comment Share on other sites More sharing options...
rockfangd Posted June 19, 2011 Author Report Share Posted June 19, 2011 must not have read the thread. I have poor range on my remotes, looking to find the antenna for the RKE to find the problem GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
Cadillac Jim Posted June 19, 2011 Report Share Posted June 19, 2011 The antenna on the RKE is on the module. You access the RKE module by removing the rear seat back. I've posted a 1997 FSM picture of the modules and relays that you access that way. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.

mike5514 Posted June 19, 2011 Report Share Posted June 19, 2011 Sorry Rock What Im trying to say is, if you reprogram the remotes It might improve your range. Mike Link to comment Share on other sites More sharing options...
rockfangd Posted June 19, 2011 Author Report Share Posted June 19, 2011 ok thanks. Have tried different remotes with same problem. I will have to pull my seatback and post more pics. I have a module I pulled from a 96 Deville and will post to see if it is the module GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
rockfangd Posted June 20, 2011 Author Report Share Posted June 20, 2011 is this the module I am supposed to be looking for? RFA(remote frequency actuation module). model# 16214709. There is plastic on one side, if I remember correctly it is for blocking interference from the metal plate. If this is the module I see no antenna coming out of it. I have also taken a picture of the inside of the unit if it might help GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
KevinW Posted June 20, 2011 Report Share Posted June 20, 2011 There's a TSB for 1996 models that addresses RKE range problems. Figure 1 shows the normal maximum operating range. Figure 2 shows where to apply the foil tape. Here's a picture of some improperly applied foil tape (looks like there's too much!) on the Electronics Bay Board of a 1996 DeVille Concours: ___________________________________________________ Link to comment Share on other sites More sharing options...
rockfangd Posted June 20, 2011 Author Report Share Posted June 20, 2011 thank you very much. So I do have the right module in the picture.. I am curious if there is any way to install an antenna from the RFA unit. Any idea where I can get the foil tape? it looks almost like 1" in the picture. Thank you very much for the pics and info, I have heard of the TSB before but one would think that there would be a better solution. I am also curious where the antenna comes from on the other members pictures. I cannot find a antenna anywhere on either my 96 or 97. where is the antenna? maybe in the RFA module? Sorry for so many questions. Making progress GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
KevinW Posted June 21, 2011 Report Share Posted June 21, 2011 In the case of a 1991 STS, the RKE module works with an antenna embedded in the rear glass, connected via a coaxial lead; the range is superior to a stock 1996 DeVille system. I retrofitted this system to my 1988 Brougham and ended up using the hood ornament as part of the antenna. I believe the newer units have internal antennas. It may help to disassemble your RFA/RKE module and conduct some experiments. ___________________________________________________ Link to comment Share on other sites More sharing options...
rockfangd Posted June 21, 2011 Author Report Share Posted June 21, 2011 I can post a pic of the inside. I think I see the antenna. I will post in the morning GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
KHE Posted June 21, 2011 Report Share Posted June 21, 2011 There is a foil tape available for sealing furnace ducts. That might work in this application. Kevin '93 Fleetwood Brougham '05 Deville '04 Deville 2013 Silverado Z71 Link to comment Share on other sites More sharing options...
rockfangd Posted June 21, 2011 Author Report Share Posted June 21, 2011 here is a pic of the inside of the RFA module. look at the left and bottom, maybe that is the antenna GM FAN FOREVER Nice, clean, luxury= fine automobile Link to comment Share on other sites More sharing options...
KevinW Posted June 22, 2011 Report Share Posted June 22, 2011 You might experiment by extending that antenna using a length of wire that's a multiple of the original length. Maybe there's a way to boost performance and keep it within the confines of the casing by using a fractal design. One might also consider increasing the transmission power of the key-fob by modifying the circuitry. ___________________________________________________ Link to comment Share on other sites More sharing options...

Cadillac Jim Posted June 22, 2011 Report Share Posted June 22, 2011 A dealer should be able to re-program the new or used RKE for your car. Call and ask, and be prepared to show your registration card with VIN so that GM can approve this. -- Click Here for CaddyInfo page on "How To" Read Your OBD Codes-- Click Here for my personal page to download my OBD code list as an Excel file, plus other Cadillac data -- See my CaddyInfo car blogs: 2011 CTS-V, 1997 ETC Yes, I was Jims_97_ETC before I changed cars.
