I need a new master ket for my lexus. Any suggestions? The dealer in San Diego just quoted me $187 for the key, $65 to cut it and about $270 to program it! Robbery!

Welcome to Club Lexus!

Buy a key off of eBay for $80, and program it yourself.

If I buy a key from eBay, how do I get it cut?
Do you know where I get the instructions to program it?

Thanks!

Sometimes you can get lucky and go to any hardware store (at least I got mine done at a local hardware store).

As for the programing instructions, hypervish listed a link to his:https://www.clublexus.com/forums/es3...mobilizer.html

You can also get the key cut at the dealership for $30, or you can find a locksmith near you who can cut "sidewinder" keys. If you read my link, you would know how to program it! lol

Hypervish, thanks for reminding me to go to your link. It was helpful but raised another question. I've lose my master key. The only key I have now is the credit card or wallet key. What does it mean to "re-flash" the ECU?

I really appreciate your help! I'm new to San Diego and will have to figure out where to take the key to.

Thanks!

If you've lost the master key, then it's time you contact the dealer.

Some dealers will replace the ECU for free, and only charge labor, and parts cost for the key. Other dealers will re-flash the ECU, meaning they will basically do a full reset (not really a reset, but those are the simplest terms I can put it into). You maybe able to find a locksmith who has the ability to re-flash the ECU.

How are you starting the car? I thought the wallet key only worked for the doors.

The wallet key works on starting the car, you just have to use the holder it comes in to disable the alarm system by holding it close to the ignition for a few seconds.

Also, those master keys are just as expensive as you listed. I bought my grandmothers 2003 ES300 and she gave me the paper work for when she had to replace her master key. We bought her an uncut key on ebay and basically the dealership just cut it and reprogrammed it. The bill came out to $160

Oh, ok. The RX and ES must have different wallet keys. The RX wallet key won't start the RX, as it won't fit in the ignition. The holder for the key also states "Not for ignition." I don't have a wallet key for the ES though, so I can't compare them.

I've just found my valet key. Can I get a aster key cut from this one without getting the car reprogrammed?

So I have a wallet key for my 2005 ES330 and I cannot get it to start the car. Light keeps flashing as if there is no key in the ignitiion. I have a master and valet key but I cannot figure out how to make the wallet key work. Is there a battery or something that needs to be replaced? Thanks!

Josh,
I've got a 2003 key and it still works so I don't think there is a battery. My guess is you aren't following the directions on the key exactly. I know i mess it it up sometimes. The mistake I usually make is not doing it within the allotted time.

Good luck!

I have tried using it several time and i have been unsuccessful. I will try it again this afternoon to see if i am missing anything.

Try this site. I used it to program my key and it worked, while other sites had wrong information posted

Key Programming

You can not program this key yourself. You will need to take your car and key to either the dealer or to a local locksmith that has the Lexus programming software


Thanks for your help though.
