noticed that i couldnt open the trunk recently with the remote button, and that the alarm had turned off the horn- then realized that the battery in the key must be getting low. i have never used the key to open the door or the trunk the old fashioned way... always use the remote.
have had the car about a year and a half-
is this normal?

 

I change mine every time I change the batteries in the smoke detector. Every time you change the clocks you should replace your battery in your remote.

 

Been using mine every day for over 2 years and it still works fine.

 

darn- i didnt get the smoke detector option in my car, and now i knew i should have!!
2 years does sound more like it-
it is pretty easy to change the battery. maybe i will do it whenever kwando changes his smoke detector batteries!

 

Why?

 

Since we have 2 of these things and I'm the only driver of this car, I alternate the remotes every year. Doing it this way you should be able to have a working remote for over 5 years.

 

So the battery doesn't die. Batteries don't cost that much. I just don't want to be stranded without a spare remote.

 

Honda remotes use a CR2025 lithium battery. They have 170mAh capacity, and keep 90% of their voltage for 80% of their life. Compared to alkaline, the performance doesn't taper off much until the very end of their life (they stay fresh). Lithium batteries don't self-discharge as much as alkalines, either... especially in your warm pocket.

If you really want to know how long the batteries will last, get a multimeter and stopwatch. Measure the current and length of time per push. Multiply it to get mA*sec units. Then take 612,000 ma*sec per battery [~] and divide it by the number you got. You will get the number of button presses per battery. All you need to do from there is figure out how long it takes you to go through that many presses. I think you will find it's about 3-5 years.

If someone actually goes through this, please post your results!

[~] (170mA*h)*(60min/hr)*(60sec/min)= 612,000 ma*sec

If you leave your keys and remote in your pocket, you might be accidently pressing on the buttons.

I don't use the Honda remote, but use an aftermarket alarm remote. I've had the batteries replaced on my Prelude alarm remote once (almost 10myears old) and the batteries on my S2000 alarm remote are still fine after 2 and a half years.
