This is for 98 and newer keys which can be programmed.

OK , i will try and give you an overview of keys since i don;t think i made one before.

You can have up to 4 key transponders and wireless remote buttons to any given vehicle.

They can be added easily in your driveway with on line instructions by following a 12 step procedure of locking/unlocking doors and what not.

The wireless alarm is a separate procedure from the vehicle transponder which arrest the engine from starting.

You can buy a fully cut used key (shell for buttons and old cut key) with or without a transponder. This will provide you a new shell if needed from your broken but you still have a working transponder and key.

You can get a key completely uncut with or without a transponder, so if you loose a key you can program the new one and replace it.

If you loose both keys and only have a master ,dealers will tell you that you have to buy a new ecu for the wireless transponder system as they need a working master to program the car.

Well they are wrong , i programmed mine with a working (grey)valet key to get a new master added .

A key is about $250 for one from the dealer.

eBay has them from

$20 for a shell only

$20-40 for a used shell and transponder

$30-50 new shell and uncut key blank no transponder( you get it cut yourself at a locksmith)

$40-100 for a new key uncut with a transponder ,sometimes new and some offer cutting for $15.

Don't pay more than this you are only driving the market price up for everyone including yourself.

Hey guys, I just purchased a 98 ES 300 a couple of weeks ago. Now i have done some research and this site has been extremely helpful. My car came with one black (master) key. I just purchased a used remote only from ebay. I wanted to know if the programming instructions were the same as those for remote keys and also if remote keys would work on my 98 ES because i have heard otherwise. THanks!
