When I bought my 98 GS4, it didn't come with a master key. So I dont have a key fob, and also my trunk button is locked. I read that the pre 2000 models you have to replace the whole key system which is very expensive. So my question is can you progam a universal keyfob to the keyless entry system in the lexus or can I buy a OEM keyfob from Sewell and just use the keyfob. Also is there a way to unlock the truck button inside the car without the master key.

 

bump any help

 

should be another latch next to your gas cover opener for the trunk release.

 

That truck latch is locked. Do you guys have any suggestion on getting a universal keyfob

 

You can get a master key cut by using the VIN through Sewell. That will allow you to open all of locks on the car. Electronics-wise, you will need a master transmitter(fob) to program additional fobs for the car to recognize.

Another option is to get can used ECU and matching fob combo and swap it out with your car to get full functionality again.

 

sorry about the bad advice, ready skills ownz me.

looks like you only have a valet key? can you just get a remote master from sewell and have his local lexus dealership program it to his car?

 

This is a really old post, if anyone knows more information about it I would appreciate it... BTW trying to get keyless entry on my 99 GS...

 

bumping again if anyone knows a less than $500 project for a 99' gs

 

I know there must be a cheaper method out there...
