have searched "keyfob"here and have read all sorts of interesting stuff, button ignitions, how to get into your car with dead battery and failed key switch, etc, etc, etc. at the risk of perhaps causing some belly laughs from those in the know, i would like to know what if any function is served by the red lens like piece on the key hinge end of the fob. it looks like it could contain a light bulb, but if it does, i can't figure out how it is activated. if it is "decorative" it could be the recipient of the "stupid part of the year" award for serving absolutely no purpose, lol.

thanks for solving this great mystery of the universe for me!!

You win!...lol. The lenses does display a small light. It's only purpose is to be able the look it to it, an know that your batteries are working in your FOB. It will blink when the batteries are good. I'm working on a small Lazer, amplified buy the red lens,....let cha know, if it works...

 

very cool, LMAO!! that's usually determined by the push of a button and the complete lack of any reaction, LOL! so now i know that i will go through life looking like a complete idiot looking at my fob while trying to lock or unlock my car just so know my batteries are good and i should expect the desired result of the pushed button. i'll bet the guy who thought that one up was paid the big bucks too, LOL! must have been devised by the battery company to insure that your batteries would have the extra draw so they would only last about 75% of the time that they would without the light and you would have to replace them much sooner, LMAO!

 

If there was no test for the battery how would you know that the fob battery was the cause of the remote locking/unlocking function not working?

 

Perhaps the simple battery checker on my work bench?? It's probably me but why do I want something that draws battery power with each button press when I want the batteries to last as long as possible?? If it was so necessary why don't all fobs from every manufacturers have "check battery" lights or indicators.?? It's different for sure. Somehow I have gotten along with a fob who's indicator light hasn't worked for a while and never since I have owned the car, so I guess I'm not smart enough to see the value of this apparently "valuable" asset. At least I now know what it is supposed to be.

 

Both of mine are only visible in nearly darkness. And then it is just hardly a flash.

Mine does not work either and hasn't for quite some time now. So I guess it only works on strong batteries, as for depleting the power in the battery I would not worry too much, my batteries have been in the fob since I purchased the car six years ago they still work and even if they do go titty up the key works just fine.

 

yup, my feelings exactly. the question was only a direct result of my curiosity and the fact that try as i might, i couldn't get anything to happen on my fob either regardless of what buttons i pushed, lol.
