Keyless Entry Range

Wildman · 11-18-2004, 08:35 PM

I searched and came up with nothing. Anybody know a way to increase the factory keyless range. Sometimes I have to be like 5 feet away from my car, (and no its not the remote battery!!) Is there a way to like, extend an antenna or anything?

mines the same

if someone knew the wiring of the car, i'm sure we could come up with a way to improve the range somehow...

all you gotta do is check out the haynes manual for a wiring diagram....

mine can reach really far not sure how far but if i park across the street i can reach it from the 4th floor without a problem.

I mean, i know this is common sense here, but i've found that my range varies depending where I am...if i'm at workk where there is alot of interference and the same with school, i really have to work at it, to get the damn thing to lock, but at my house and at my parents house, there appears to be much more range.

A guy had told me about this trick with alarms don't know if it'd work with keyless entry but you can try.

Make sure your on pavement not grass. Stick the remote under your chin, the end of the remote that you'd point at the car.....touching underneath your chin and press the button. Seems silly but it does work on alarms and don't be hiding behind a tree or building trying. Try in a parking lot.

LOL, that turns you into a giant antenna!!

lol yea i had a friend tell me that once too, and ive tried it but i still am not too sure about it..........

Maybe I'll just wire one of those mini satellite dishes to it, and I can point it right at my car then hit the button :P

cherrington17 · 11-19-2004, 06:09 PM

doing that actually uses the back of your skull as a satellite dish...lol it works, i did it personally when a friend told me the same thing.

a guy i work with has a minivan he did this to....
if you want to try this with your spare remote(if you have one) open the case up, and look at the circuit board. there should be a small trace the almost completely circles the outside of the board. that is the "antenna". take a high gauge wire, with as little insulation as possible and solder it to the spot where the trace started on the board. then have the wire stick out some from the remote case (about an inch or two) that should drastically improve your range.

i was thinking about doing it, but decided not to.. i'm too lazy...lol i can still hit mine from like 20 ft away.

this would be very simple if somebody could come up with a schematic for the remote and or figure out where the receiver is in the car for it. Does it use the antennas in the rear window?

11-19-2004, 10:12 PM

no i dont think it uses anything in the rear windows thats the defroster and antenna for the radio.......what cherrington said sounds like something id like 2 try......

Anybody know what kind of signal the keys use. Frequency? I thought it was more of a IR type device at first.

cherrington17 · 11-20-2004, 10:40 AM

heres a pic of my own "keyfob" i guess they are called.

FormulaNERD · 11-20-2004, 12:59 PM

it's uses low range radio frequency (rf)

an IR device would be horrible, especially on sunny days, and you'd also have to have an LED exposed like in a tv remote.

Yeah i realized that quickly. It always seems to vary on range. Mine sometimes can reach quite a ways...like across a big parking lot. Depends on what interference is floating through the air I guess.

My circuit baord doesnt look like that

Possible differences in years?
