In one day key fob stopped lock and unlock the car, panic button doesn’t work as well.
I made new key and programmed it, but new key doesn’t work too.
Mechanic inspected bought keys, and bought have a good battery, clean contacts, and have signal when I press the buttons. Also I can start the car with both keys

All fuses looks good, fuse box clean.

Maybe someone knows what’s going on

Keys, new and old will start the car because they have a security chip in them. Remote functions probably not working due to RF hub or associated wiring. RF hub receives the signal from remote. Unfortunately I don’t know anything about a 2011 RF hub or if it can be reset or tested.

And I found obd2 code, B1A08
So something wrong, but I don’t know what

B1a08 - Remote keyless entry FOB 1 performance. Usually happens from too many button presses out of range and signal to receiver gets scrambled. Try clearing and then using the fob while in range and see if code comes back.

Thanks
I cleared it, but didn’t check if code came back. But fob doesn’t work anyway

You don't have any working fobs? If that's the case I'd assume that the rf hub may be bad. Could try to disconnecting the truck battery and pressing the brake pedal to drain all power and then reconnect to see if it reboots the trucks modules.

The truck is probably messing with you because you keep insulting it by calling it a car.

So I googled a 2011 Ram and it appears that there is no RF hub. Have you checked fuse M38? Supposedly that’s the fuse for the door locks. Can you lock and unlock the doors using the switches on the doors? If the door switches work the locks then the information I read claims the WIN (wireless integrated node) module receives the signals from the fobs and may be the problem. It could also be a TIPM issue.

Yes, I’ve checked the m38. It was first what I checked. And I can lock and unlock door with the switch.
I don’t think what it’s a win, because I can start the car. So it might be RF hub.
So I’m going to remove back seats and check the hub

You may want to research the information online. From what I found trucks before 2013 have a WIN module not an RF hub. Supposedly the WIN module is what receives the fob signals on a 2011. You may be removing the rear seats for no solution.

2011 Ram, i believe, does not have an RF Hub behind the Rear Seat, next to the Cab Vents.

Instead the Ignition Switch is the WIN Module

2011 Dodge Ram WIN video


Notice, that he said that HIS Company would not CLEAN or repair it, if something went wrong, his company would be Liable.

You on the other hand you can clean it & you may never have an issue.

There are Youtube Videos that show how to possibly fix it

A replacement WIN, can be costly

So I research the information too. So I have ram 1500 2011 sport. And I have remote start, so might be I have RF hub behind the rear seats.

On this video, a bit different key. I have the same key fob like model since 2013.

You can have remote start without having an RF hub. The WIN module controls the remote start. In the first picture below it shows the remote start connection on a 2011 WIN module. It’s the pink connector. In the second picture below is what your key probably looks like. This type key was used with WIN modules and RF hubs.

RF hubs weren’t used till the 2013 model. Also you stated you programmed a new key. Did you use Alfa OBD to program it? If you have an RF hub you need an electronic interface to talk to the RF hub, it’s a much more detailed procedure with an RF hub versus a WIN module. Does your remote start work from your key fob? If it doesn’t I’m guessing your WIN module is bad.

The ignition switch behind the dash is much smaller on 2013 and newer vehicles because they have a RF hub. If you pull the lower dash panel and you have a rather large black plastic box for the ignition switch you have a WIN module as it handles the signal functions from the key fobs. It could also be a wiring issue in the TIPM but likely the WIN module.

There are 2 types of key to start the ignition

This is called a Transponder Key, it has a CHIP inside of it
