Ok here what I did.

After the mechanic installed the Locktech and test the start function, I tested it again at the shop. I pulled the 1st lock until hear the clicked sound, then I pushed the 2nd lock to lock the 1st lock. (Complete locked)

Try start the engine by push the start engine button. Electric system functioning, but engine not start. Success.

I release the 2nd lock, then release the 1st lock. Now push the start engine button. Electric system functioning, and engine start. Success. (Of course it will start because the pedal lock is unlocked)

Ok now the remote start function.

I lock the 1st and 2nd lock. (Complete locked). Close the door and lock it by pressing the lock button at the door handle.

Now from the remote key, I press Lock (car blink once), and then press the remote start button. Electric system functioning, and engine start. Success!

I enter the car, release the 2nd and 1st lock. Press brake and push start engine button, and all system run smoothly. Success!

All tests completed successfully...

Edit: Other than Locktech, you can try Aorto. Our friend here, Sawamura using Aorto and have no problem with remote start function.

PS: But make sure to check the pedal lock you buy is really Locktech Civic 2016 (PS) written at the box. Because before this I want to install Locktech and the seller said ok. But when he bring out the box, the brand is written in Thai. Looks like Locktech but but it is not Locktech. So I cancelled to install the pedal lock with him.
