Here a collection of El-50448 GM TPMS relearn tool good feedbacks. Thanks to the real users’ contribution.


  1. works on truck and car: Simple and inexpensive but works great. Much better than going to the dealer or a tire store just to get your pressure sensors reset. I used it on my truck and my wife’s car and it only took a few minutes to reset all four wheels on each.

Well worth the money.

  1. with correct low battery display: I’ve never been able to get my TP sensors to program using the “let air out” method on my 2007 Tahoe. Before I had this tool, I would just remember which tires were which when I rotated them, but no longer. Now, I can reprogram them in just a few seconds and the dash display correctly indicates which tire is low. This tool should have come with the vehicle.
  1. Easy to use: The operation of this product is simple and straightforward. As stated it’s hard to get excited about spending this amount of money just to rotate tires, but considering what dealers would charge, it would not take many trips service visits to pay for the unit. As far as working it does exactly what it says it will do with no drama. Put the vehicle in reset mode and push the button on the unit following directions outlined in the car owners manual.
  1. I could not believe I needed a special tool to rotate my tires. From what I understand 2010 (2011?) and older vehicles, you can use any big magnet to reset your Tire Pressure Sensors. 2011 (2012?) and up to at least my 2013 Silverado, you need one of these gizmos. This one works like a champ, and is the one I found referenced through a GM website.

It is a simple process:
1) Put your key in the ignition, and turn it to run.
2) Press your lock and unlock buttons on your remote until the truck chirps. (There are a few other ways too, but this was easiest).
3) Start with the left front tire; the blinker light for that tire should light up to let you know which tire needs programming. Cool right?
4) Put this gizmo to the tire next to the stem, and press the button. After 3 seconds or so, the truck chirps
4) Then the front right blinker is on, and thats your next tire. Press the gizmo to the tire and press the button. Continue on to the rear right, and finish with the rear left. All the while following the blinker. Takes all of 3 minutes.
On one hand $50+ is a lot to ensure my tire pressure sensors are all aligned properly (I rarely look at them. On the other hand, I have a new tool and no strangers need to touch my truck.

  1. Wide GM vehicle coverage: The deflate method is verified ok only on Chevrolet Volt 2011 year, with the El-50448 TPMS relearn tool, I could get the 4 TPMS programmed in less than one minute. El-50448 could program TPMS on GM 2010-2013 year.

you can find the tool at any GM dealership, or buy it off online e.g I have a link here:

 El-50448 GM TPMS relearn tool price is 50usd by Paypal with delivery (15-20 working days) and pay more shipping fee; you could receive the package in 3-5 working days by DHL. PS: when you receive the package you can find it includes not charger and battery, if you need them, you need pay additional 10 usd.

Step 1: Correct Chip Data

Install battery for wireless universal remote key.

Place remote key into VVDI2 programmer
Auto detect chip type
Press the remote control buttons, LED will keep flashing, it means that it’s into correction status
Signal acquisition success. LED indicator will flash rapidly.
Data correction is completed, ready to decode and copy

Step 2: Copy and Decode Chip

Put the chip with a battery installed into the remote control
Put the original car key into VVDI2 key programmer for identification
Click on Start Copy in VVDI 2 interface
To collect information in the car and put the collector into VVDI2 (because we have collected data in Step 1, it’s ok to put the Xhorse remote collector into vvdi2)
Put the original key into vvdi2 key programmer again
Connect to the network, to start decoding online
Decode chip success
Put Xhorse remote key collector into VVDI2

Put the new remote key into vvdi2 programmer
Select Genearte Remote function
Select region, make and model
Select Generate remote-wireless

Use special equipment to program the remote, i.e OBDSTAR Key Master or Xtool X100 Pad etc.
Xhorse wireless universal remote can copy a chip after regeneration as remote control, new equipment –Xhorse VVDI Key Tool remote generator will add this function.
