Car Forum / Saab Cars / November 2007Keyless Entry Range
We have a 2001 9-5 with keyless entry. Manual says it only works short range, and it does, and this seems to be intentional. Around 15-30 feet. Today, while running errands, I was listening to CarTalk (http://www.cartalk.org/) and someone called in about the remote. They said their geek son said that if you point it at your chin, the range is longer. Klick and Klack said putting it in your open mouth is much better. Today, while leaving a church picnic, I was about 100 feet or more from the car, too far for the keyless entry to work. So, I tried it. It didn't work. I opened my mouth, stuck it in there and tried again. The doors opened! Charles Sorry, http://www.cartalk.com/ is a better link. Charles > We have a 2001 9-5 with keyless entry.

The keyless remote uses radio waves. My (2001 9-5 Aero) key has always had terrible range. Occasionally it will open from 20-30' away, but more often I have to be nearly within touching range before it will finally work. I'll have to try the "open mouth" trick. >> well, there is a thing in optics called constructive interference of >> spherical waves > Except this isn't optics.

I sense a competition coming up? My 9000 Aero will open at about 30m, or from inside our house while the car is outside!

Last night was a "good night" for my 9-5 -- it responded to the key when I was 30' ~= 10m away. That's an unusually good range for my car. Pointing it at my open mouth had absolutely no effect on the range. >No competition! Last night was a "good night" for my 9-5 -- it responded >to the key when I was 30' ~= 10m away.

Just 3' or so vastly increases range. |
