Key Fob Problems

Maintenance/Repairs

My husband and I bought a 2006 Jeep Commander last May that only came with 1 key fob. It starts the vehicle just fine but the keyless entry works intermittently, with it unlocking easier than locking. With my husband’s habit of losing keys and thinking the fob may just be wearing out, we bought several blanks on eBay and had them cut and programmed. They work but no more so than the original, meaning the unlock function is still less picky than the lock function. About a week ago, my husband’s replacement fob stopped working all together so we just used mine. A couple of days later mine has stopped functioning. After trying new batteries, I got the original fob that came with the Jeep and it still locks and unlocks but the same as before, intermittently. I took the fobs to the auto parts store and my husband’s fob didn’t show that the RF is working on it but my fob and the original fob did. I don’t know much about keyless entry but I would like to figure out why it only sometimes works. It has a re-manufactured 3.7 liter engine that we had a great mechanic put in back in August and after my husband bought a remote start to install we discovered it already has one but we have no fobs for it or even know if it’s getting power so I was wondering if that might be part of the issue. We have not installed the one he bought. Also, every several weeks it will have a time where it’ll take up to 5 or 6 tries to start and I was wondering if that could be related to the fobs too. Some days where it doesn’t want to kick over the first time is just one go round and it’s fine after and other times it doesn’t want to start well for most of the day, then the next day it starts fine for several weeks. Haven’t discussed that with the mechanic yet as I’m just now needing to go in for an oil change. Thanks for the help!
