RE: Electronic Keyless Remote
There is abundant experience and forums discussing the Electronic Smart Keys.
In no case can a key purchased on eBay be re-keyed to operate in a new car. The keys can be programmed only once.
What's not clear is whether the mechanical portion of the key is mis-cut, or the electronic portion has gremlins.
Normally the mechanical key isn't used - it's really for emergencies. The Smart Key is really 2 devices. The remote has 2 flat nickel sized batteries that may need replacing. The ignition key portion is not dependent on batteries and instead has a coil that interfaces with the ignition switch.
The mechanical mini-key can be re-cut at a dealer or a designated locksmith, but the elecronic Smart Key is manufactured by the factory from your VIN number.
Order an additional, not a replacement key, or your existing keys will stop working.
The best price out there is around $130 to $140.
From what you say, I would check the batteries first and maybe you can dodge this bullet with $10 worth of batteries. [:I]
