Post subject:  Fob Remote Malfunction

My husband was at the hardware store when he heard a car alarm go off, and lo and behold it was our 05 Prius (without smart key). He couldn't get it to shut off, so he took out the little key, got in and put the fob in and started the car. We assumed it was the fob battery, but each time we insert the new battery, the car starts honking again. The spare fob doesn't work either--won't lock or unlock the car, nor shut off the honking. I suppose I am doomed to pay a visit to the dealer, but just thought I would ask here first.

Is the 12v battery the original one? If so, I suspect that it is failing and needs to be replaced. A bad 12v battery will cause all sorts of strange things.

Agreed. Look here for two versions of the battery selftest procedure (no tools required);

12V battery replaced, no change. I had to get the car back for some emergency transportation. Taking it back today and hoping they can figure it out.

So I found do-it-yourself programming instructions here: viewtopic.php?f=16&t=4320&start=15

...but not sure of the procedure for two fobs that won't lock/unlock but will start the car. Would rather not pay the dealer if I can get away with it.

I suggest seeing a dealer. I think you have another issue other than the fobs.

Call some other dealers for prices... Also, ask whoever does the work to see if there are any codes that kick out. If so, post them.

AACK! Both keys need to be replaced! Need advice on how to avoid paying $300 apiece! Thanks.

What happened to them? I haven't heard of fobs going bad. On occasion an ECU fails, but not the fobs. There must be more to this story...

The dealer says that one is corroded, must have gotten wet (I doubt it), the other they have no idea. Gave me a dire warning that one or both could at any time fail and not be able to start the car. I decided to take my chances. But, good news: when I got the car home, I discovered that one remote is working again! I'll just always take both keys along just in case, in the meantime if anyone knows anything about aftermarket/used keys, I would appreciate it if you would share.

You can get a fob (black logo - non SKS) from eBay. It can be programmed to start the car, but the lock and unlock buttons will not work. The price you were quoted from the dealer sounds like the SKS (silver logo) fob. I suggest that you buy one from the dealer and have them program it. That way you know you have at least one good fob.

They tell me they went off the VIN, so I think that's the price. I think I will shop around.

Didn't I read instructions on here somewhere for programming the door lock function?
