best place I have found for both price and quality is https://www.dealextreme.com/details.dx/sku.16372. under 4 bucks and all four I have gotten have seemed to be OEM or better.

How about getting an aftermarket (or OEM) keyless entry remote NOT part of the key?
I think i remember reading about getting any remote with the same FCC ID number and you can program it to do the lock/unlock, while you use the durable but compatible chip key blank (Camry or aftermarket) for the ignition.
It adds bulk of the extra remote, but the oem design is crap and was from day one.
I found the electronic module in the key has to be very close to the ignition switch for it to work. Hanging it on a keychain would make it convenient, but you'll need to hold it close every time you start.
Solid keys with transponder chips built in might work, but if they do they might need to be programmed by the dealer. I just bought new keys for my '03 4R, solid rubber heads with transponders, the dealer had to program them.
I hope to get these cut to the VIN, I've had the dealer do several I bought there, they haven't been easy to work with. I've heard that locksmiths can cut to a VIN, haven't tried that.

On my '02 Lexus key there is a little screw on the logo side of the fob just above the key. Vehicle has 68-69k miles on it and the key still looks new. I wonder if it's the same fob design as on the Cruiser?
The transponder only needs to be near the ignition for starting, not running. You can program the transponder keys yourself. I don't remember the formula, but if you search, it's here.![]()
My new OEM was considerably stronger than older case I had. They actually modded it!
Some of the aftermarket shanks have straight ends (where the jagged portion starts) that don't always work with the ignitions.
