Extend range on key FOB

[firstcomesl]

2000 GMC Yukon Denali. Love my truck but, I have a problem with my key FOB. I think I'm still using original key fob. It has no range. Must be right next to driver door window before it unlocks. Maybe 2 foot range. I have cleaned all internal contacts, replaced batteries, done everything I can think of to add range. Does anyone have any suggestions. Get newer fob? Can I add antenna? Where is receiver in truck? Anyone have better range with aftermarket fob? I am interested in any suggestions. Thanks in advance.

Some say holding it under your chin with your mouth open works but I’m not sure I’d want to do that. Most likely the fob needs replacing. No big deal they’re everywhere.

I have a 2002 Z71, original owner, and have gone through several key fobs in its lifetime. These are readily available, and can be self-programmed at home using a special sequence of key on, key off, along with manual door lock/unlock. I have a range of at least 30'+, and my oldest (working) replacement fob is 5 years old. All key fobs must be programmed at the same time (in sequence), which is great in case you have an existing fob that is lost or stolen. This one comes in black, blue, or red.

I've got 2007 Z71 and have replaced 1 of the 2 original FOBs, easy to program and my replacement works from inside the house to remote start the car in the driveway 30'-40' away

Does "everything I can think of" include reprogramming the old one?

I don't know if it'll work, but it's free.

Thanks for your responses. I did reprogram about a year ago. I'll try again and let you know. For background, I bought this truck 7 years ago with only 100k miles on odometer. Only has 140k now. Daily driver, but less than 15-20 miles per day. After these responses I did go on amazon and purchased new fob for less than $10. Haven't got it yet, but will let you know. For 10 bucks I'll try anything. I have never gotten more than 5-6 feet of distance on this current fob. Does anyone know what distance you should expect on this type of oem fob? Maybe their efficiency falls off over age. Thanks again.

FYI Here is the one I purchased for my 2007 had good luck with. I never did cut the key that came with it, just programmed the FOB and attached it to my original OEM key.

oem fob should go 30-40ft
there are tons of options out there, my Viper goes up to 1 mile. with added smart start it can be done worldwide.

I'm also wondering if it works any better when you're not at the house.

I've been reading, for years, about the congestion with-in the designated consumer radio frequencies. So, I wonder if there's some nearby source of interference, at the house.

in the Freq spectrum that the fob use's probably not unless you are running some high power illegal ham or cb equipment
most oem fobs are in the mid 300-450mhz uhf/fm short range, similar to tpms freq
compared to my Viper which is in the 1.6~1.7ghz range

I didn't think it likely, but, sometimes, all you can do is start eliminating possibilities.

I recently ordered the fob that looks like the K2XX for my 07. It works great.

I got one of the 2015+ style key fobs from boost auto idk why but it reads 3x farther then what my old key fob did
For example I would have to go by the side door to the carport to remote start the Tahoe and after I could remote start it from the living room halfway through the house no issues and in a parking lot could unlock or start it from 200+ feet away! Definitely worth the 60$ or whatever it was to buy it!

that is a good option, I have found that the 2015+ fobs tend to wear quickly so I changed mine to a AJT case, then there is nothing to "wear" they are injection molded and come in a variety of colors. $40 (case only). mine is about 3 1/2 years old and has been proven to be pretty much unbreakable, been dropped numerous times.

seems like an expensive big square pocket snagging key fob to me

I keep mine on a hook on my belt loop.. lol

doesn't snag on anything, there are no sharp edges it is completely smooth on all sides, buttons are recessed, lightweight. I bought that to replace the fob for the 2018 that looked it had been to war, no more "rubber" buttons.
it has the same button configuration as the boost auto fob
the buttons are embossed/engraved whatever, no print to wear off
I was skeptical at first that it might break but this thing has proven to be durable, hasn't come loose or anything.

 

[gooffeyguy]

Still big and square compared to an OE ~99-14 teardrop shaped fob if you ask me.

I like small rounded fobs, lol

02 mustang fob, although square it's small and rounded
01 yukon fob
12 yukon fob
15 Acadia fob

All original, OE

 

[Big Mama]

I got the same one Wes and Trey did. I don’t know how it works so much better but they’re right. I can unlock or remote start big mama from my living room. Here they are side by side. Not much difference in size and definitely doesn’t snag on anything.

 

[gooffeyguy]

A lot different in size, lol.

I guess none of mine have gotten to the crappy range point yet. They still work from anywhere in my house or the other side of a parking lot.
