1) It took abt 15 mins to install.
2) Warranty is one-year. But warranty card is in Thai!

Don't think it'll have any problems. See item 4 for the reason.
3) To lock, just pull the lever next to the lock chamber. This lifts the steel piece behind the brake paddle up into lock position. Then cannot press the brake and ignition is shut off. The lever is spring loaded, so it does not stick out and hit your leg when you get in later. There's a slight free play but cannot press brake to stop. I tried in the car park in my condo! Had to free gear and pull handbrake. He he he... Refer to pic below for visual explanation.

4) No drilling, not welding, no cutting of wires. Ignition cut is thru Y-socket. Steering column brace is screwed on. The screws are all covered/hidden when the lock is engaged. Cannot try to screw it out. Besides, the position of the lock is a little difficult for someone to try and remove the lock or saw it off.
BTW, the key is a waveblade key...like our car key!!
Hope this answers your question.
sebaver installed the same lock i think. I heard it's arnd RM400. Anyway, just hv to make sure you are still able to press the brake all the way to the end, so ABS could be triggered to not void the brake warranty.
