Hello everyone. I am posting this thread because of a problem I was having with my key fobs and the battery’s.
This problem started with my '14 Rubi many years ago. I turned off the horn alert when locking or unlocking with the key fob. If I am close enough to hear the doors lock, why do I need to have the horn blow and scare anyone near me as several cars do to me each day. In Europe, it's against the law to sound the horn when locking or unlocking your car and I TOTALLY AGREED!! Notice, past tense!
So begins my story. After about 3 months of flawless operation with the key fobs, I started having problems with the batteries dyeing, or so I thought. I would replace the battery and the fob would again work for another 3-4 months.
Then after about 2-3 years, the new batteries seemed like they were only lasting 2-3 weeks before I would start having problems. My solution to this problem was to PUSH THE BUTTONS HARDER! UNLOCK, RELOCK until I heard the locks ‘LOCK’! It seemed to work but I think it was only a psychological band aid. I went through several (20-30) batteries.
Now this problem has struck my new ’18 JKU. It’s a year old and I have changed the batteries in the fobs 6-7 times. Each time I would change the batteries, they would work fine for a couple of weeks, then they would stop working. Same thing, push the buttons harder.
Recently, I started checking the batteries with a volt meter and noting that the voltage is exactly the same as a brand new battery. Without replacing the battery, I took my knife and bent the tangs that the battery touches up a very little bit towards the battery, to make a better connection. This worked!! The fob started working as if I had replaced the battery.
So, what am I led to believe. NOT having the horn sound when walking away from the jeep, sometimes I don’t hear the locks. I stop, listen, unlock and relock and pushing the buttons harder. “FLATENING OUT THE TANGS.” Hmm. I now know the reason for the horn sounding when locking or unlocking vehicles. I will be turning that back on and NEVER pushing the buttons on the fobs harder than a little girl would. Pushing them harder does nothing but screw things up. Problem Solved!!
