I have a 2012 SRT Challenger with a strange issue. My remote start is intermittent depending on the direction I walk towards the car. If coming at it from the front, it does not seem to get the signal to start, but if I come at it from the rear, it starts right up.

So I wonder if it's an issue with the remote batteries...anyone else with something similar? Where is the receiver unit on the car?

My remote start seems to work ok but sometimes, not often, when I try to set the alarm, it can take a few button pushes to get it to set. And in order to set it, I have to aim the remote in the direction of the dash where the VIN tag and gage cluster is located. Unlocking the car, no problems. Trunk release, no problems. It's funny too as my Magnum SRT and Ram SRT did the same thing...

I was taught by an installer if you're a distance away from the vehicle, hold the remote to the vein on the side of your neck and press the button as it considerably extends the range of the transmitter. I can walk out of the mall press the button and see no lights flash, hold it to my neck and the truck responds. Your body acts as the antenna.
As you said it may need batteries and some items eat batteries faster than others.

Just replace the fob battery before you do anything else.
Also if you have any aftermarket electronics in the car, it can affect or even totally swamp the remote signal. Items such as: Trinity tuner, cell phone charger, cigar lighter to USB adapter, aftermarket HIDs, etc.

Update: I've found that the direction I approach the car in the parking lot makes a difference. If I approach the front of the car, I get much better results vs. coming at it from the rear.

So the issue seems intermittent...some days it will start fine from the door leading to our parking lot. Other days it won't start until I'm standing in front of the car.

I've replaced my batteries, and tried the other FOB.

Any thoughts?

Sounds more like the batt or a key fob about to fail. If you have a new batt in there, make sure you have the lil prong on the inside touching the batt. If all that is done and well. You may just need a new fob.

I love it! True.

Always just odd how the voltage is higher around the neck vein ;)

Also just some info:
I have seen the door handle for the passive entry being the problem, but rare.
More info: May not be related to your concern however.

Some early reports indicate short range operation from the RKE FOBik, operation intermittent at
