What is the PCB?

Thank you.

This is a PCB from a car key.

This SMD component is missing from the second key (somebody cut the case too deep when trying to open it and damaged this component) and I'm trying to find out what it is so I can get it and repair it.

 

Show a picture of the key that has the component on it, easier to guess if we can see it.
If that IS the good key, then it looks like a jumper or something, hard to tell. Measure across it with a voltmeter in ohms mode and in diode mode (both ways in diode mode)

The picture in the post has the component marked.

It's green with a black square on the side.

Here's a picture from another angle.
