Lol no I don't use it everyday .
But I would gladly give it 4.5 out of 5 if it had the interface and Jeep, Chrysler,Dodge Ram, Ford capabilities right out the box. Ha!

Of course then it would be $378 - $478...

It's a nice unit but always room for improvement. For what you get it is hard to beat at current price point.

Default Program manually?

Is it possible to program the key fobs manually without a scanner?

There are no RKE self-programming instructions for this vehicle.

yea thats what everyone said, no one had to download anything. The seller messaged me back and i had to pull the memory card and download the program then update everything on the card then put it back in the scanner, i will test it shortly

IT WORKS! Only, when you have wireless communication from the BCM.
>>>Check/Clean BCM/ANTENNA contacts.<<<

Well i pulled the panel and there was no water intrusion but someone had been messing with the antenna before i bought it. Its a discontinued part (25792166). Tried plugging it back in and laying it close to me then tried to program the fobs again and still nothing... guess im just SOL

also was told this is what picks up the signal for the tpms sensors and why people will get the random tpms death light when the signal drops
