Ya, Bryan, I know...It's very scarry..!!
You know, I actually stood beside the mechanic while he did the entire procedure....!!!
Thank goodness, I got a young guy who knew exactly what he was doing..

I think we all need to have a moment of silent prayer for Ron today....

But, you know, maybe, just maybe, it was all slight of hand and it was done just to impress me.. Mmmmmmmm.. I wonder !!!

You guys are a hoot. I may just hang around and watch. It's always good to see where those hidden clips and tabs are just in case you ever need to pull something apart yourself. 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'

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)...

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.
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!!!!

Thanks for following up. I was hoping you were still out there. I was aware of the general theories of the way radio waves travel but not really versed on the specifics. We used the theories in planning how to defeat radars when planning combat missions for our aircrews. We actually don't defeat them so much as hide from them (behind mountains, trees, etc) but we had to be careful cuz those pesky radio waves bounce off of damn near anything). Anyway, we had "geeks" like you who got into the specifics and programmed our computers or answered our questions. I'm looking forward to hearing how your testing turns out but it'll wait until you're feeling better. Take your time and feel better.

I'm hoping to back good as new again early next month. Sorry about being long winded on theories! I'm not really on RF engineer, just an old RF field technician, who has worked in both broadcasting and cellular industries. Hope your Easter (and everybody else's) is good!
#146 of 167 Quick Update (Partial)
Apr 08, 2007 (10:07 am)
Partial update here...took my car in for the 2.2 hrs worth of labor called for to repair the RKE/Remote Start/Tire Pressure Monitor system. After over 5 hrs, I got the call to come pick up my car but the tech was unable to get the programming completed. Since it was a Saturday, Chevy tech support wasn't in to help them out so I'll have to take it back this week for them to finish it up. Now...get this. They're not sure that they can even get any help from tech support without having my car there so I will have to leave it with them again. Fortunately, they have agreed to get me a rental THIS time around (the 3rd time). I haven't done an actual range test yet but I did use the FOB a couple times on the way out to the car from a range further than I'm used to them consistently working and they worked flawlessly. That's a good sign. I have the new FOBs with the stars and instructions printed on the back. They also pointed out that they installed a new antenna that basically looks like a strip of black duct tape on the windshield running down from the top of the windshield behind the mirror. Very clean and neat and unnoticeable if you aren't looking for it.
I'll follow up once they get the tire pressure monitor programmed. I'll probably test the range on the way home that day.
Good tings, guys...good tings... (The Sopranos comes on tonight!) Do they really talk like that in Jersey, Bryan?
P.S. - Oh, and Happy Easter and Passover.

Ron, yes they do talk like that and those scenes in the beginning of the New jersey Turnpike and the other locations they show, I've been to most of them. I live about 6 miles from where they shoot most of the scenes and Tony's house is in West Caldwell, about 3 miles from my house. And , I do believe the real Soprano types would have wacked a few Dealership mechanics!! .............My Impala is doing fine!!!.....Tony would never drive an SS though!
