    I have a key without the remote attached; my other one broke; so I bought a key with remote off ebay; they sent instructions, but I've done them numerous times and they don't work. Please help! Actually I bought two remotes/keys and I wanted to get them to work the remote lock unlock before I had the keys cut on them. Thanks

    ok lets see if i understand , you have 2 uncut remote keys and hopefully 1 old key that at least can start the car , if so : here we go , read this till you think you can almost do it without the directions , follow these instruction very carefully . it is very tricky ...

    1.) remove key from ignition switch , ensure driver's door is open and unlocked and all other doors are closed . insert the "working" key into ignition switch and then remove it , go to step 2 .
    2.) complete the following within 40 seconds or less . press your door panel power door lock switch to LOCK and UNLOCK within 1 second , repeat this process till it has been done 5 times , ( lock/unlock within 1 second ,lock/unlock within 1 second ,lock/unlock within 1 second ,lock/unlock within 1 second ,lock/unlock within 1 second ).now close and open the door .go to next step
    3.) repeat step 2 except do not close and open the door , when you have completed repeating the step 2 except for closing and opening the door , insert the working key into ignition switch and turn ignition switch to ON and back to Lock (from on to lock within 1 second), once more , ON and back to LOCK (from on to lock within 1 second) , now remove key from ignition switch .go to next step .
    4.) complete this step within 40 seconds , to confirm proper initiation , door locks will cycle 2 times . now press transmitter LOCK & UNLOCK buttons simultainiously for 1+1/2 seconds , then within 3 seconds press any transmitter button for at least 1 second , then go to next step .
    5.) if within 3 seconds door locks cycle 1 time , new transmitter code has been successfully accepted . go to next step . ** if door locks cycle 2 times , the new transmitter code was NOT accepted .... to program an additional transmitter or to make a second attempt at the 1st transmitter repeat step 4 within 40 seconds . if done go to next step .
    6.) close door or insert working key into ignition to exit programming .
    7.) verify operation of transmitters .

    well hopefully you did it , and they work , i have proof read this like 10 times and tried to make sure each step was explained correctly , and as easily as possible yet to the point . if this doesn't work for you , you might try let someone else try , or a locksmith , or the dealer , and let them cut the keys afterwards .

    Thanks For using FIX YA !

    this is quite a tricky procedure to program a remote for your car , due to complexity and variation of instructions , i ask , are you replacing old remote , adding a 2nd remote ? or ?

    Thank you thank you thank you.. my remote key got wet and i was told i needed a whole new freaking key $265 at lexus!!! Talked to a locksmith who was going to charge $200 for the whole thing and $40 to program. I was not about to pay that money and super bumbed that I would be putting my key in the door every damed time I wanted to enter my car. I found this post, worked the first time. I am forever indebted to you. Your car knowledge has just made my day.

Change your battery first, then try again. The codes don`t normally erase on their own.
I had a new master key programed this week and watched the process at the dealership. Mine was done with the same diagnostic code reader they use for the entire vehicle, attached under dash via cable,with the master key along side it is like a giant meter. It took about 7 minutes
