All door lock black buttons on outside & fobs not working

i would check all fuses.

 

Both remotes don't work? Pressing the remote buttons? Did they ever work?

 

Deducing that you recently acquired this used car?

Did the remote Lock/Unlock ever work from the FOB, when you pressed the button?

Did you check the fuses with a DVM (Digital Volt Meter) to ensure continuity? A visual check is usually worthless.

What color is the Toyota logo on the back of the FOB? Black or Silver?

If Silver, and the SKS never worked, you need to go to the dealer to have the SKS ECU cleared and reprogramed with your current SKS FOB(s). If you only have one silver FOB, best to buy a used or new one, before going to the dealer to have the SKS ECU cleared and reprogrammed. Once the Prius learns the SKS FOBs, best to buy NEW replacement SKS FOBs; the car can learn new SKS FOBs w/o dealer intervention; learning used requires dealer help.

If Black, these are meant for a non-SKS Prius and you obviously will not have any SKS functionality. You will have remote lock/unlock. Having a non-SKS FOB defeats the purpose of SKS, so best to get an SKS FOB.​

 

You would need to reseed the car to make it work. Those may or may not be the original fobs for the car.

 

Price shop the dealer fee for reseeding the SKS. Likely $200 range. See if they will include the key cut for your blanks that come with the new SKS fobs; they will have to look-up the key code, as you most likely do not have it, since you lack original keys. Make sure all existing learned fobs are deleted before they start the reprogramming process. Actually the beat up sks fobs could be included in the relearning process if you wanted. Hmm, I wonder if the previous person just put on a silver sks back into a non-sks fob?

Look for dealer service discount coupons on various dealer websites. Typically all Toy dealers will honor another Toy dealer service coupon/part coupon.

Internet search "OEM Toyota Parts". You'll get lots of hits for actual toy dealers selling online at a substantial discounted rate vs their retail parts counter. There are also the annoying everything under the sun large box auto parts stores too. There is a Toy Florida dealer.

 

Part in the key that is used for SKS system is totally separated for the part that is used when key is inserted into the slot. So you could just have two broken keys if key only works if inserted.

I would start by testing it with another key. Since your key works inserted you can use it to pare another key.

 

The SKS portion is a passive, energy free system, that requires a reader (car door, trunk, center console). When the correct SKS fob is in range, the exterior buttons or the Start button will function. The battery that is in the remote is only used to send a signal to remotely lock/unlock the doors or have the car's horn sound for a distance, say 100feet.

The previous owner might have lost her original two SKS fobs, and just picked up used eBay fobs. The problem with this is the SKS function won't work. Remotely locking/unlocking can be made to work, but the convenient SKS portion will not, until the car's SKS ECU are reset to learn whatever SKS fobs are being presented for learning. This is why you must stick the fob into the ignition slot to Start the car. If the SKS ECU learned your fob, you would not be here incorrectly thinking the SKS buttons are broken.

What you are describing is what many others have described when getting used SKS fobs from eBay: they loss of SKS functionality because their car has not learned the used SKS fob.

 

You can buy used fobs to replace your current mangled up fobs when you are reseeding. Don't need to buy new

 

like the dentist.

 

I know all about the dentist. You will have to mortgage the farm if you listen to him.

 

right, and you have no idea what's going on in there, just a boat payment.
