Hi there. Due to lost my both 2002 Lexus es300 keys, I just replace aftermarket ignition lock which came with 2 New keys and Engine control.But it's doesn't start my car. Anyone can advice what I do?

Your screwed dude ... You have to find a qualified Locksmith or Visit a Lexus Dealer. The Anti-theft system will not allow you to start the car unless the proper code is entered into the key. Some insurance companies will provide names of companies who specialize in those issues ... good luck

Well, it's doesn't happened like this, I mean screwed. Actually the 3 parts I replaced are perfect since I do realize that after insert the key to ignition the security light stoped blinking.which means the computer did recognize the key. and why it's not start engine or any other electrical could be the main fuse has Been blown since I tried to hot wire my car at very first...I am working on this right now. Let's see.

I have the same problem. Mine starts then shuts down. But will run when I give it gas. Think I am going to have to take it to the lexus dealership. Huh?

You need to reset the fuel pump code to read the new key the security system is keeping the fuel pump from turning on.

I have a solid red light before the key is in the ignition when I go to turn it he will crank but won't start then there's a blinking light it's giving me a pause excuse me A1 then a 1/2 can a 1 and I want to kind of a blink any idea what else could it be
