If you plan on programming the key fob yourself (without a professional), then you would most likely need a BRAND NEW keyfob. Programming a Used Keyfob is very complicated
The keyfobs are different....if you have SKS functions or no SKS functions. Amazon should sell both....around $100
i think i have sks but as a back up i dont car about any features except starting car i have the spare physical key...
SKS will allow you to start the car without putting the keyfob into the keyslot. Verify the part, but I think this is what you need. Toyota Parts - Camelback Toyota Parts - Genuine OEM Parts - Free Shipping
I is kind of torn and beat up and i had suspected it might be setting off my alarm not sure if it was fob or weak 12v battery....
If you have an aftermarket alarm in the car, it would not be the Keyfob that would affect it. Most likely a 12v or another issue. If the keyfob is just beat up and ugly looking, just put that in the drawer as the spare and start using the other one. You don't need a good looking spare....just a functional one to use in those "rare" occasions.
