I have installed almost 4 years now, my experience ..

-1st month I have facing problem .... that is the when unlock there is a sensor which connect to “start” car .. when something wrong .. sometime can start sometime can not .. it took me few time to chk, 1st we thought is Toyota immobilizer problem ..after chk found is actually the lock .. when unlock have to make sure the lock press till down ... To avoid this in future, I ask the shop remove it that wire, eft only lock ... Sad smile

-I find that when at night a bit difficult to get the key into hole ...Open-mouthed smile
