after a while you battery on the remote loses power then the distance shortens. chage your battery on the remote, it will change the distance like when your car was new.

 

oh now thats a good idea, i was too lazy to do that so i just got lojack

 

on my 99, i cant see it under the seat...

 

Yes, & no, my old remote works from 5ft the brand new one, works from 5ft. But, yes, when it's going dead the range goes down.

 

2K S4, def. a nice write up bro... I just did this today and it works great : I get about 55-60 paces from the front now (165-180ft?)!!! I'll try her from the back tomorrow (no pun intended) and let ya'll know.

 

So were is the battery in the key i pulled it apart and it looked likr it was a sealed part

 

Thanks for the write up...this will be my first mod to my baby!

 

I was also pissed about the range and I found the antenna under the bumper. I then took a 14 guage solid copper wire and soldered it to the antenna and ran the wire through the top of my rear window and stripped the insulation off the wire. I went from 3ft to about 15ft and I was wondering what went wrong. Am I better of using braided speaker cable then the 14g solid or did I lengthen the cable to much (about 6ft)? I even put in fresh batteries in the remote.

 

I don't have an S4 remote to try this with - although I'm working on changing that! But the chin trick always worked with my other keyless remotes. I could lock my old Lexus from my apartment, which was 200 feet away from my parking spot.

 

Cbass: The antenna length needs to be proportional to the wavelength of the signal. 6 ft is ~twice the suggested length so that should be close but that does not include the stock 8 inches. Stranded vs solid wire should not make a difference. I bet 6 ft is too long but I am not sure.

germania: I have had no luck extending my range by holding the remote to my head, chin, temple, ... Can anyone else vouch for this method? I performed this mod and definately saw an improvement.
