I recently bought a silver 98 GS400 from a member here and i have a couple problems, and my key won't program, but he said he took the ECU out once and it blew a couple fuses, but anyway

i have 2 problems
1. my master key, doesnt unlock or lock the door when i press the button, i have to manually do that... i searched around and tried to do the tutorial but it still wont program.. i also have a spare ECU with a master key

my question is, can i just program my current master key so that it works? why doesnt the tutorial work?

if i can't can i just replace the old ECU with the new one and itll work?? it came with a master key... will i have to reflash the ECU or anything like that? how do i do that? Also how do i program the key that cme with it to work?

2. the 15a cig fuse and the 7.5a fuse above it keeps blowing out, even when i put on new ones, i want to be able to use the cig lighter to charge my phone.. where do i start by looking for the problem?

ive tried searching everywhere, if anyone can help that would be great

also could the ecu being messed up have anything to do with the cig fuse always popping everytime i turn on my ignition?

I wouldn't think that the ecu would be the cause of the cig lighter popping fuses. Most likely a short. If the car has had any stereo or accessory rewiring or tapping done in the past it could be a lose or exposed wire or connection.

I would start super easy for that one, just use a meter to check the power feed to the cig lighter and see if it reads a short.

I've seen like three different tutorials for programming keys on this board, that each have slightly different steps for some reason. I have not had to try to reprogram anything yet, but just a thought to may look up and try a different tutorial.

my car does this but with as much electrical work as i have had done or done myself i just pulled the fuse and moved on. i spent like 20 mins trying to track the cause and even had another member help me and we couldnt figure it out so i pulled the fuse and moved on.....no BTW ecu wont affect this
