Hyundai Coupe GL 2.0 2005: Factory Remote Control Fails Despite New CR2032 Batteries

Question

Hello, I have a big problem I can't open the car with the factory remote control. Car is a Hyundai Coupe GL 2.0 2005. I have already replaced 2x batteries with CR2032 and nothing diode on the remote control flashes and the car does not open. Is this a symptom of a broken pilot? Is there any opening alternative, I heard that the code could have been unloaded, for example, I put photos of the pilot, it may be helpful.

Hello
Try it this way.
After replacing the battery, turn the key to position II and press the open or close button once. The immobilizer indicator will blink once. Turn off the key.
Check if it worked and let me know.
greetings

So I opened the car with the key and began to squeal. I opened the mask, disconnected the battery and peace, plug it in and leave again ... will it be long? I feel like a thief. I talked to a guest on the phone and said that you need to check if the remote control sends a signal.

I received information from Hyundai that I should hold both buttons for 5 seconds, the action was unsuccessful. It seems to me that I have damaged electronics in the remote control alone, I will not do anything more, I have to do checking / soldering.

Ok, my wife helped me disarm the alarm

It turned out that both remote controls had damaged electrical connections. After dismantling the remote control, it was necessary to press the battery firmly to the PCB. Thank you colleague for a hint from the first position in the ignition. Two remote controls are going to be repaired from what I read on the HYundai forum - this is a common problem in this model.

Let it ... the alarm specialist checked the car's remote controls and apparently they work and send a signal. He said they were all right and that there must be something wrong in the car ehhh ...

Listen to whether the factory alarm can only be repaired by a salon or can some alarm specialist deal with it? I am looking for someone from Zielona Góra and the surrounding area or from the province Lubuskie.

It may sound funny ... but I think someone tried to prompt me and my colleagues at the car park. Namely, a few people at the same time could not close using the car remote control. Strange, as if the signal jammer is working somewhere is it possible?

Very likely.
