My Lexus IS250 fob buttons are not working, but when pressing them red light appears, do you know how to fix it? it’s connected to car electricity. ---

More power is required to unlock the doors with the remote then to start the car. It could still be the battery. ---

A new fob battery is a cheap fix if it works. If not, we you are only out a few bucks, and it would need replacement eventually anyway. I don’t know how long Lexus fob batteries last. ---

The instructions to replace the battery are in the Owners Manual in your glove box. It’s quite easy. ---

Does the car sound a tone when you press the unlock button? ---

The car came with 2 fobs originally. Do you have the other one? If it doesn’t work with both fobs, then the problem is in the car. If it’s in the car, you probably need a shop to fix it. ---

No I have only one fob, what problem may be from in car (door sensors and start/stop are working nice)? ---

This is not likely a do it yourself fix. A Lexus dealer will be your best bet to get this solved and it won’t be cheap . At the same time you might as well get another FOB. ---

So you think it’s fob problem and not a car? ---

You could try buying a second fob. It can be programmed by the dealer or a locksmith. Just any locksmith won’t cut it. He has to be registered with the state, at least where I live. ---

You said you only have one FOB , that is why you should get another while you are having this problem fixed . I suspect you are not in the United States . If another country that makes a little difficult to make good suggestions. I think the receiver in the vehicle is the problem . ---

Yeah, I bought a car from the USA and brought to Armenia with one fob ☹, is fob button receiver different from the keyless receiver? ---

I guess you are saying you can start the car but the FOB will not unlock the doors . Yes , they are two separate things and it still will take a shop to solve this . Since this was a US vehicle it makes it all the possible that a dealer is your only source of actual help. ---
