Keyless Entry keypad

Yea, but the keypad is out there in the heat/cold 100% of the time compared to a fob which is generally kept at a pretty moderate temperature.

I recall a 10 year life on the battery.  I do not recall where I got that information.

If you get 6 years on new fobs with the push button start, you'd make a fortune selling that battery.  

 

We have customers in weekly with 2 and 3 year old vehicles needing new fob batteries.  They don't last anymore with keyless start.  The old stuff used to go 5-10 years not needing a fob battery.  

I actually got a " replace FOB battery soon"  39 months on the battery, probably got another few months before it goes out. Will need to replace it prior to our summer activities. 

 

Does anyone know if the key pad only uses energy when in use or does it constantly use energy like our FOBs?

I had one installed when I purchased truck. Basically its a regular remote entry fob (non passive) that is in the form of a keypad, and it sticks to the outside. You can definatly lock the doors with your keyfob inside or with the truck running as I do it all the time. Usefull when you are on the beach or walking the dogs and you dont want to loose the keyfob while you are doing so. Also good when you want to pick up the truck from service after hours and they can put the fob in console and lock the doors for you and when you get there, you use the keypad to unlock. Been almost 3 years and the batteries are still good. Does not use much power at all since it is in sleep mode when you are not pressing buttons. I use mine several times a day when I walk out to truck without my keys. If you press the 2 bottom keys at same time it will lock the doors with the fob inside. If you press and hold the bottom 2 keys at same time it will even fold the mirrors in like a normal remote does.

Hi, I have the same GM 85540054 (was 23473339) keypad entry on my Chevy Traverse. Was told that the batteries aren’t replaceable. BUT… I took the keypad off with dental floss, took off the cover, pried/popped the 12 little tabs one by one and the unit opened up. Standard CR2032 battery (you can see where it is between the two 3M tape parts! Replaced battery and popped it all back together. Didn’t need to re-program it either! Forgot to take a photo while replacing the battery but YES, battery is replaceable on GM/Chevy/Buick keypad entry!
