I bought a 2013 RAV4 LE and purchased a second set of wheels, tires and TPMS sensors (OEM type) back in 2016.
This worked fine and Costco (where I bought both sets of tires) would reprogram them when they swapped out wheels.
When the batteries on my original TPMS sensors started failing I decided to get a cloneable set from Autel so I wouldn't have to mess with reprogramming twice a year.
I purchased 4 MX type sensors and the MaxiTPMS PAD from Amazon back in April 2022 (about $200) and have been trying to get them to work ever since.
The PAD is supposed to be able to program sensors via entered ID number or clone from an existing sensor either loose or on a wheel.
Since I had the winter sensor IDs recorded I just programmed the new MX sensors directly then installed them in the summer set which were already on the car.
The default option said "hex" and I was not sure so I called and waited forever to talk to an Autel rep who didn't seem to know what I was talking about but kept saying "use the default". No work. So I tried programming them with the non-hex selection. Still no work.
I took it down to Costco who was willing to reprogram them for me. They could read the sensors but not upload them to the vehicle system. Their recommendation at that point was to take it to the dealer but I knew all they would tell me is I should buy the OEM sensors.
At this point I figured I had better try a direct clone process.
Dealing with the sensors while in the vehicle is tricky. You have a laptop connected to this USB pad and it tends to pick up sensors on other wheels.
So after messing about with it and getting frustrated I decided to remove each wheel, remove the MX sensor from the wheel, and clone each independently to the winter wheels a good distance away from and vehicles. What a pain but I finally got that done. I tried Costco to get them programmed again but they had the same error as before.
So I put the winter wheels inside the car and had Costco program the winter wheels.
That looked like it was going to work but after a bit of driving the blinking light came on again (I suspect it never worked and failed when it first tried to verify)
I called Autel tech support and waited again forever on the phone and finally got somebody on the line.
He listened to my story and then suggested I get an Autel ODBII programming tool and give that a try. I was not about to go buy another tool that may or may not fix the problem.
I asked for a refund. When I told him I bought the products through Amazon he said there was nothing they would do because Amazon was not an authorized retailer.
I have had good luck with Autel products in the past but I am certainly not impressed with their customer service.
Not sure about next steps. For those who say "just ignore the light" if this car was still mine I would probably do that but my daughter drives it now and I want TPMS to work because I can't check the pressure often.
 
I have to sets of wheels - one with original sensors and one with cloned Autel ones - and everythinh works as it should.

"HEX" relates how the IDs are written down. If the IDs include numbers and the letters ABCDEF - then it is written in HEX. If it is just numbers - then it is DEC. The HEX notanion is more common and this is how it is usually written on the sensors.

When you say "no work" - what exactly is failing? You should be more specific.

TPMS would not work if you drive with two sets of wheels in the car cloned to the same IDs.

What you should do:

1. Get the sensor IDs from your winter wheels. You can either read them with MaxiPAD or rely on your records - but make sure you are correct.
2. Program the Autel sensors to the same IDs. This usually requires the sensors laying on the PAD - afaik it does not work with the sensors installed.
3. Make sure the car is programmed to the same IDs - this requires connection via OBD2 with Techstream or a special tool.

No work = TPMS light comes on and then starts blinking - same as when not programmed to the right sensors or when a sensor battery loses charge. My understanding is that the blinking light indicates something wrong with the system not any tires losing pressure. The scenario you describe is exactly the first scenario I tried but I used the HEX as the Autel tech recommended but my IDs are all numbers so maybe I need to switch to the DEC. I believe I tried that but was getting very frustrated by that point and could have made a mistake. I will try again when I get the car back. Thanks for the response and ideas as well as confirming nit worked for someone.

Part of the problem was there were too many variables with a lot of work to test each scenario (i.e. HEX/DEC, 3 DIFFERENT 2013 RAV4 AUTEL menu selections for programming, on-car/off-car, etc.). At this point if Autel will not support their product because I bought from Amazon I may be better off to wait until the weather cools off and swap the winter tires on the car and make sure the programming is correct to those codes. Then I can program again and swap tires to test. If I can't get this working I may try to replace the batteries in the original OEM sensors. I have seen a couple videos of how to do that. Looks messy but I am already into this for too much $$.
 
The pad is a bit of a kluge, and not the way I'd be going.

I have an Autel TS508 (had a TS 408 a few years prior), and it works like gangbusters - on our various Toyota vehicles over the years, our previous Honda and the last 3 Subaru's. I've made clones and simply new random hex ID sensors with MX-1 units, and had no problems with them..... except with one set of 4 that were not intended to be sold in the US market. An ebay seller was peddling Asian market sensors in the USA, and the tools will not work with them.

You might try giving the Autel rep the serial numbers of the sensors to see if they are legit. If ebay guys can do it, probably a fly-by-night Amazon seller might too.

I finally got the Autel sensors to work. I had the numbers written down from the winter set of TPMS sensors so I removed each summer wheel, used the jack and car frame to break the bead (this actually worked well), Re-programmed the Autel sensors on the summer wheels to the winter numbers (not using "HEX" mode this time), re-seated the beads and installed the summer tires all-around. Initially, this did NOT work but at this point I was able to take the car to my tire shop and they were able to successfully program the car to the sensors.

notes:
1. I did NOT remove the tires from the wheels, just broke the bead so I could get the Autel Pad in close enough to reliably program the sensors. The docs say you can program mounted tires but I could not reliably do so even after multiple attempts.
2. Not sure but I suspect if the tire location is changed on these older TPMS systems the car has to be reprogrammed to the new locations. I am assuming that was why the sensors did not work once I cloned them correctly.
3. I will be interesting to see if I have to reprogram the car next time the tires are swapped.

Thanks for the info regarding NOT using the "hex" mode when programming. That was what gave me enough confidence to try again. Coordinating getting the car, swapping tires, breaking the beads, etc. is a bit of a chore.
 
I recently bought the Auteltpms TS508. Tried to read the sensors on the 2017 RAV4 LE FWD.
Had it set to Toyota, Rav4, 2013 to 2018 and none of the sensors read correctly.
Set the tool to Toyota, Rav4, 2013 to 2015 and it read four tires but not the spare.
I do not know why

So, could be possible the programming to the Rav4 (years) was incorrect??
And as far as I know, hex or decimal doesn't matter.
Manufacturers may use different notations but it is still same numbers
The tool should have converted it to read correctly on the sensor.
If new sensors were cloned correctly
then vehicle should have recognized the winter tire same as the summer tires
