Unhappy Teardrop keyfob range VERY low on wrx?

Hi guys, YES I searched, could not find anything definitive.

I just picked up a 2002 Impreza WRX. The keyfob only works 1-2 feet from the car and I am wondering what this could be. I tried with the doors open and it's not any different. The keyfob is not the issue - I reprogrammed another good keyfob to the car and it has the same low range, and it works 100-200 feet at least on my 2005 WRX.

Where is the wireless control module located on this car, under the panel near the e-brake? Or under the driver's side kick panel? Anyone have any experience extending its antenna or have any other ideas?

Thanks in advance!

If memory serves me right, it's an Alpine remote design. (Blue and orange buttons?) And they tend to suffer range issues when battery's are low, or poor battery contact. They can also break the antenna circut if dropped hard.

The keyless entry module is under the drivers side dash, not sure on antenna?

Originally it probably came with that oblong remote, but I was given a teardrop style one. I know the fob is fine because I reprogrammed another fob with excellent range and it had the same 1-2 foot range on this car. I also tried different battery, no different. So I believe it is something internal to the car. The car is also equipped with a factory alarm if that matters.

Keyfob that came with the car when I bought it:

Keyfob I tried that I know is good:

Again I know both fobs are OK .

Stupid idea, and not really a fix, hold the FOB under your chin (touching it) and check range. Your body becomes sorta an antenna, not sure where your receiver is.....

If you want to spend the $$, there's a switchblade mod you can do that incorporates a legacy key.

^Except that OP has already stated that they are pretty sure it's the car's module and not the fob that's causing the problem.

I tried it before, but it didn't make a difference. Many people online claim it helped them, but it didn't do anything for me.

I hope some super guru will correct me if I'm wrong. But 02-04? Had the blue/orange remote, while it wasn't till '05 the teardrop came out.
I don't know if the newer remote could program, but could play a role?

Non the less, it's clear the module in the car and the antenna are connected, since you can use the remote close. Remote issue? Heavy metallic tint? Aliens?

Obviously you are not familiar with antenna theory. Also your body is mainly water, how well would the remote work when submerged, assuming it's waterproof? To test the theory start with KY Jelly, insert the fob up your....... NVM

Car does have a tint but with the windows down and doors open the range is the same. I think the type of remote shouldn't matter if it's programmed to the vehicle.

Per cars101:
ALPINE SYSTEM, new starting in 1999, used through 2004
information is always subject to change and correction Used on:
Legacy, Outback all models 1999-2004
Forester 2001-2004
Impreza 2002-2004
1999 Legacy only: Passive arming of the optional 1999 alarm system.
The dealer could program the alarm to arm automatically whether the doors are locked or not. In this mode the doors must be manually locked or using the power lock button or the remote.
In Passive Mode the system will automatically activate in one minute but will not lock the doors. it will arm the alarm even if the doors are not locked. Lock the doors using the power lock switch with the door open. If you are using the remote to lock the doors, there would be no reason to set Passive Mode because locking with the remote would arm the alarm anyway so I'm not sure why this function exists.... To open the doors use the remote or the key, but then the alarm will go off and you'll need
To set Passive Mode:
Open driver's door and remove the plastic step sill that curves up toward the front.
Connect the single-pole white connectors.
the plain gray buttons were used 99-01, colored buttons for 2002-04

replacement note: this style remote has been discontinued and replaced by the new 'TEARDROP' style in late 2009. See your local dealer.

D-Rock, I said correct me if I'm wrong! I think I nailed it.... Good bit of extra info no doubt.

But what if I told you, the type of remote might in fact matter... Seriously, it's the only theory I have left. The car came from the factory with the Alpine Blue/Orange remote, and has been reprogrammed with a teardrop. Who knows how well the replacement teardrop (non-Alpine) style performs with the old Alpine system.

If it was mine, I would try these things in this order. I'd swap brand new batteries. Then delete all fobs and reprogram. Then track down a blue/orange remote... Then screw this, aftermarket for 100.00.....

I already tried new batteries but it didn't change. I'll try to get the blue orange one but i feel that it won't make a difference

How about some Frankenstein type chaos!? Install two CR2016 battery's instead of one CR2032.(tight fit) This will double battery voltage from 3 to 6... It might just work. I believe the transmitter can handle it, but try at your own discretion.

That's actually what I did It extended the range maybe a half foot to a foot? Not what I was looking for though :-\

I have the same problem with same fob on my 06 STI. Doesn't really bother me a whole lot but it can be a bit annoying sometimes.

Put it against your head will amplify the signal. Don't ask me why.

90% of the responses you've recieved are useless bs. If you don't know what you're talking about why respond?

The tear drop remote has been working flawless for my bugeye for years. Look elsewhere that is not the issue.

Yes I know hence why I asked where the antenna is .. Although I don't know if that is the most logical way to address the issue because I think that is not the root cause
