Hyundai Santa fe remote faulty

[mojsterb]

Hello,

I am here to ask you for help. I am learning these things :)
I have remote for Hyundai Santa fe 2007, which does not work.
No RF frequency output, LED does not light. I measured current, it is 5mA, also when press one of button.
I resoldered main IC, but no differences.

I suspect problem in saw resonator. Is possible that current is 5mA when resonator is removed from PCB?

Any help will be great.

Did you try make a shortcut for example by a tweezers? Maybe microswitches are faulty?

Where to make shortcut (for testing?)?
Microswitches are ok, I desoldered them and also 5mA current.

I thought about make a shortcut on microswitches soldering pads. Several times I've got sitation when microswitches looks good, but not working corr3ctly. Also measure the current when clicking switch/making shortcut. It should encrasing

As I said no RF signal from remote, LED not blink and also I desolder switches and current is always 5mA.
Is problem in main IC (maybe someone made short on pins)?
