Replying to: quietpro (Apr 02, 2007 5:20 pm) Well done my friend...There's no way they are going to mess around with any of us here, especially with our knowledge on this particular FOB fix. It seems to me, that WE can now teach them (GM) a thing or two .....!! What...!! Not use your VIN for this, and, LOW PROFILE TIRES!!!! ....Pretty lame, huh !! Oh well.. Typical!!! Ya, while it may call for 2.2 hours in their book, if you get a good guy here, once your car gets into the shop, it wont take any longer than 1.2 hours...I would certainly hang around and watch this if possible. Well, Ron, unless they do things differently there, this was not my experience...The Actual reciever module/box that they will replace is found inside the top right side of the dash and the coax cable antenna is found on the top left side the of dash close to the window. Soooooooooo, yes, while both of the A-Pillar covers come off ....so does the top of the dash..!! Hang on now..!! Let us know how you made out... Don't you just love your Chevy..!! Frank

Ok, are you ready for this.....remember now, this is for a direct front Fob shot... I got 175 feet at the office, then it went down to 129 1/2 feet at the Shopping Mall, and now just this morning, before everyone arrived, I got an amazing 209 feet.  With the same Fob , Ron.. It boggles the mind !! I think I'll stop here.... Frank

Replying to: mymitties (Apr 03, 2007 3:57 am) I specifically asked about the dash because I was going to have them put the anti-itch tape in to stop the clicking/popping while they had it apart. Frank, your long shot with the lot empty may have been due to lack of interference. Remember the post by our wire head friend with all the knowledge? He is going to test with his equipment to try to determine if these systems are affected by other systems. It makes perfect sense that they would be and your testing (and my experiences) seem to reflect that as well. Y'all keep smilin'  Ron |

Replying to: quietpro (Apr 03, 2007 5:38 pm) Ya, I know... Although You may have asked him about the dash coming out, remember, that this is the same GM guy that told you that the Message showing .. " Service Tire Pressure Monitor System " on your screen was because of your low profile tires...!!!! Very, very, scarry.. Now, I Don't want to sound pushy here by any means, but, make absolutely sure that they install the replacement receiver module/box over in the dash (passenger-side)... Well....good luck..... Frank

Replying to: quietpro (Apr 03, 2007 5:38 pm) Just to give you an update, I haven't had a chance to check into relative interference/noise levels yet. I'm still laid up with injuries. But when I'm back 100%. I'll be looking into it. Frank, Thanks for your report on your key-fob ranges. I'm glad you got yours fixed! I agree with Ron, that once you have a good antenna,receiver and fobs, the range could still vary some due external interference, or even the signal bouncing off of the other cars in the lots and arriving at the antenna in your car at slightly different times. When this happens, the signals could cancel each other out,either slightly (reducing your range) or almost completely. This effect is termed as "multipath". I'm sure you are familiar with it. If you listen to FM radio you hear it while driving down the road and you start to hear the station fading with a "hissing" noise. It's also somewhat simulair to listening to AM radio stations at night, that fade in and out. The fade effect is caused by two signals from the same transmitter (the primary ground-wave signal and the secondary sky-wave signal) cancelling each other out at the receiver. Back to our problems. In the cell phone industry, they know that multipaths effects the range of your cell phone call. So they add an extra antenna and receiver at the cell phone tower to keep your cell phone signal from dissipearing completely due to multi-path. Maybe that's what GM should do in the future to increase range for their remote key-fob systems. About the TPM problems, I'm ure the antenna/receivers are really shot if it can't pick up the RF coming from the tire sensors. By the way. I wonder how those tire pressure sensors are powered? Maybe a small hearing aid battery ? Sorry, I kind of dribble on at times! I appreciate all the posts! And I too love my 06 Impala SS!!!!
