Key Fob Cover Fit for 2004-2009 Toyota Prius, Key Fob Replacement Shell Keyless Entry with Blank Key, Key Fobs Case 3 Button(MOZB31EG, MOZB21TG)

This was the exact replacement I needed for my broken fob and it works great! I was glad to find it at this price and especially happy I didn't have to go to the dealership for it.

The programming for step 1 went perfectly, just as described; for step 2 there were some issues--first there was no red signal when I pressed either key on the new FOB, so I replaced the battery with a new battery and now I had the red signal but try as often as I might, I could not successfully program the new FOB for remote keyless entry. After steps 10 and 11 as described on the product page, instead of one series of lock/unlock I received 2 series in rapid succession and the keyless entry wouldn't work. I reached out to the vendor and they responded very quickly, but the video they sent didn't help, it only covered step 1. Now, for some reason that I can't explain I felt this FOB should work, I researched other product responses and saw the instructions (the image I uploaded) from info someone else had posted. I tried that too, and it didn't work. Following a hunch, I did more research and read a response where the customer did the sequence quickly with little gap, especially steps 18 and 19 (from image I posted)--that for me, was the formula. Pressing the lock and unlock key simultaneously on the old FOB and then very quickly pressing lock and unlock keys simultaneously on new FOB. Then press only the "lock" on the new key and I heard a single lock. THEN, I opened and closed the door one more time to seal the program. Waited about 30 seconds and everything worked on the new FOB. Keyless entry (touching the door handle to unlock door) pressing buttons to lock/unlock and keyless ignition. So as you can see, there was some work on my part to get this functioning, but I'm giving this 5 stars, because the unit, did, eventually work as described and customer services reached out to me and stayed in contact. So, if the programming steps listed on product page don't work for step 2--consider this alternative.

Great product

The tolerance for the back cover/latch wasn't perfect and I could not remove it easily. Used a large screwdriver to pry it off, and damaged the shell a bit. The tolerance was poor enough that I ended up snapping a piece of retaining plastic that allowed the lid to lock in place. The spring was very strong.As another reviewer mentioned, the original back cover and latch had the Toyota logo and it fit in the new shell. Perfect! And the key fit as well! Perfect! Now I can make a spare key which will be helpful for running, surfing, etc.To open the old key, all I had to do was use two thin screwdrivers and rotate them to snap the super glue. I put a thick Costco rag under for stability, friction, and not to lose parts. Circuit board was pretty self-explanatory - pushing on the buttons outside while making my way around the board allowed it to pop out easily.For the small passive proximity chip, I saw in a youtube video that a pointy razor blade should suffice. No need to cut at the glue like the Amazon video. Dug at the chip from the bottom of the chip, where it was not restricted by glue. Gave it a tiny bit more leverage than I was comfortable with (given it was my first time) which allowed the chip to pitch-rotate enough to pull it out. It's hard plastic so it's not easily damaged, but need to be cautious nonetheless as it's not replaceable. The molding in the new shell wasn't 100% and didn't hold it perfectly flush, but it was 95% and it doesn't really matter how flush it is.Buttons feel better than the original. There is some matte quality to it, not sure if it will wear smooth over time. The panic button is better than the original, as the old one had a tendency to fall out. The new one is attached to the case like the others and sticks out more. As such, they actually realized that this could be triggered by accident and made it extremely difficult to push - but not too difficult in an emergency situation. I pushed hard and the red LED turned on.Speak of the LED, the LED hole works perfectly. It lights every time I push a button.Great! Thanks so much for an excellent product. You have taken a good product and made it better.

Got this because my primary key looked pretty rough and I was afraid that sand/water/dust was going to get inside and damage it. I had to use pliers and a box cutter to get the old one apart (the person who had the car before me apparently GLUED it together). This new one is a perfect fit, easy to assemble, & feels durable. Don’t forget to move the little magnet(?) thing in the triangle shaped section at the bottom! I drove around some today and my key worked normally.

This was very easy to do, the hardest part is getting the old glued case apart. A very sharp pocket knife was able to slide into and pry open a space between the two parts housing the board and chip, and a little twisting of the knife got the job done.The new case snaps into place now, so no need to glue.Two parts were not mentioned in the instructions. One is the O-ring around the battery, which would help keep moisture out. The other was also on both the old key fobs. When the circuit board comes out, check to see if there is a small white piece on a small cylindrical post on the unlock feature, and between the lock and unlock features. The piece has a ring that fits onto the post, and a foot that fits into the space between the edge of the post and the back of the unlock button. I believe it provides support for the functions so that they will last longer.I could find no mention of either of these two parts in any of the videos, but since they were in the original key, it stands to reason they were carefully thought out by the designers of the key and serve a purpose.Bought a new case when the tab broke off the back. So easy to fix.
