Replacement Key Housings
Hello everyone, I recently purchased a 2001 RX300 that came with 2 keys. One seems to be the original, but the key is separated from the alarm/battery housing. The battery seems to be glued to one of the pieces of the casing and I haven't tried to pry it out yet. The 2nd key is a similar looking key but without the alarm. The salesman said he had it made for $75 so it could communicate with the car. Is it possible to start the car from just a regular cut key? or does it need the transponder to work?
I'm also looking to buy a new casing for the original key so I can use the stock alarm. I've been looking at two choices on eBay.
Lexus 3 button Key Shell Blade
That one looks just like my original, I'm guessing I could just take it to a locksmith with my original broken one and have him cut & replace it?
Lexus Switchblade Remote Flip Key
I am interested in this form factor just because the newer cars use it, but was wondering if it would be just as easy to cut and replace the battery/transponder onto this model type of key. Anyone tried these for there older lexus'?

You can buy key covers with dummy keys from ebay , http://www.sparecarkeys.com/contact_us.php or sewell lexus parts (i don't have url). Also do a search on this forum and you will come across many suggestions. I think the weakest thing Lexus made was the keys cases and then recently they changed to FOBs, really good move.

The switch-blade is after market product. OEM and its copies are like the one you are holding. I hope no one has glued the electronics in the half shell.
The cheapest way is to buy an un-cut after market and have it cut and transfer the electronics. You may have to search who can cut the key for you and dealership might refuse to cut some thing that is not OEM or something that you did not buy from them.
The electronics have remote function and the imobilizer tag and that is why it needs to be near the ignition key hole, else you will crank and crank but the vehicle would not catch on.

So the key extra key the salesman had made does have something in it that requires ignition, would it have cost him much more extra to get one that was alarm compatible (with buttons)?

I live in a small town about an hour from Austin, but make trips through and to Austin somewhat frequently. Could you suggest any local locksmiths that could cut and transfer the electronics from my original key to either of the housings? The switchblade housing from ebay I posted seems to have the buttons in the same area as my original. Looks like the swap should be pretty simple? at least for a locksmith?

Sorry, I could not understand your second paragraph. The key is a key which is personalized by the humps and the cuts. The electronics part is the remote and there is a small magnetic transponder for imobilizer. Master key (whose magnetic transponder is registered in the ECU) can authorize other transponder to allow engine to be started.
Oh one more thing, take the key you want copied (duplicated) ,,, you have the valet key and the other key(s).

I bought an OEM key and Lexus of Austin cut the key for me. When I tried calling locksmith, they tried to convince me that they need to program the key [I was in the same boat as you ... just cut the key]. So I can not recommend any one. Transferring the electronics is as easy as replacing the battery ... all you need is a right size screwdriver.

So am I understanding that any of the blank uncut on Ebay will work, but they have to be cut. Once cut you can take the transponder from the old remote and put it into the new one right? Does the new cut key have to be programmed? And am i correct and saying that once transferred into the new shell, the transponder works as it should?

So the answer to your last question is 'yes'.

I bought this last June, no issues. $18.50 for 2 precut keys, including shipping.

If you don't know your key code take your registration to the dealer, they can look it up from the VIN.
A few minutes to swap in the electronics and you're done.

Hello, has anyone tried those fold-able / flip/ folding remote keys? Does it work well? A near locksmith said transmitter might be a little too far away inside the case and it might not work at all. So does anyone knows for sure about this? This is an image of the key I'm considering... thanks !

I have one that's disintegrated, too. Couldn't I transfer the metal blade to a new shell, along with the electronics? Seems like that would be easier than getting new keys cut. I know it's not currently attached to either piece of the shell, but I don't know if the blades in the replacements are removable, or not.
