Little bit out back ground..

2013 MDX Elite, 140,000 km. Great vehicle, no issues other than this.

- Compustar remote starter installed at the dealership, works great.
- Car is unmolested, no accidents, or funny wiring to my knowledge.

Here's the issue.

Few months ago, I noticed my factory Acura key fob, would only lock and unlock sometimes.. at random. I found myself occasionally using the compustar remote to lock and unlock.

One day, the factory remote fully stopped working, wouldn't lock, wouldn't unlock, no power rear gate, nothing. Leading up to this, I did notice decreased range, but I figured it was a dying remote battery.

Now, just a few days ago, my MDX has fully forgotten keyless memory, and now I cannot even enter the sub menus toggle thing such as auto unlock, light settings, steering wheel settings etc.. I tried to reset to default, and it said failed. This is on multiple keys too..

The cars battery has not been very strong lately, so I purchased an AGM for it today, R&R'd the battery, and now it says I cannot adjust the settings because it cannot link to a remote. Mind you, the car is on and driving..

Has anyone experienced this issue? I want to bring it to the dealer soon, I just hope it's not something retarded.

Try re-programming your keyfobs and linking them to the memory settings.

Here's my video starting where I go in details on how to do it:
