TPMS are only re programmable with aftermarket software. Used to be with OE diagnostic software but not anymore.
Don't know what you are driving, but here is copy from my 2017 Ford manual.
I know, I know ... reading manuals is not popular thing.

Performing the System Reset Procedure - Single Rear Wheel
Read the entire procedure before attempting.
Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park in a safe location where you can easily get to all four tires and have access to an air pump.
Place the ignition in the off position and keep the key in the ignition.
Cycle the ignition to the on position with the engine off.
Turn the hazard flashers on then off three times. You must accomplish this within 10 seconds. If you successfully enter the reset mode, the horn sounds once, the system indicator flashes and a message shows in the information display. If this does not occur, please try again starting at step 2. If after repeated attempts to enter the reset mode, the horn does not sound, the system indicator does not flash and no message shows in the information display, seek service from your authorized dealer.
Train the tire pressure monitoring system sensors in the tires using the following system reset sequence starting with the left front tire in the following clockwise order: Left front - driver side front tire, Right front - passenger side front tire, Right rear - passenger side rear tire, Left rear - driver side rear tire.
Remove the valve cap from the valve stem on the left front tire. Decrease the air pressure until the horn sounds.
Note: The single horn tone confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and you must repeat it.
Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds.
Remove the valve cap from the valve stem on the right rear tire. Decrease the air pressure until the horn sounds.
Remove the valve cap from the valve stem on the left rear tire. Decrease the air pressure until the horn sounds. Training is complete after the horn sounds for the last tire trained, driver side rear tire, the system indicator stops flashing, and a message shows in the information display.
Turn the ignition off. If two short horn beeps are heard, the reset procedure was unsuccessful and you must repeat it. If after repeating the procedure and two short beeps are heard when the ignition is turned to off, seek assistance from your authorized dealer.
Set all four tires to the recommended air pressure as indicated on the Safety Compliance Certification Label, affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver seating position or Tire Label located on the B-Pillar or the edge of the driver door.

Performing the System Reset Procedure - Dual Rear Wheel
For further information see Understanding Your Tire Pressure Monitoring System and refer to Dual Rear Wheel, earlier in this section.
Read the entire procedure before attempting.
Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then park in a safe location where you can easily get to all six tires and have access to an air pump.
Place the ignition in the off position and keep the key in the ignition.
Cycle the ignition to the on position with the engine off.
Turn the hazard flashers on then off three times. You must accomplish this within 10 seconds.

Train the tire pressure monitoring system sensors in the tires using the following system reset sequence starting with the left front tire in the following order: Left front - driver side front tire, Right front - passenger side front tire, Right outer rear -passenger side rear outer tire, Right inner rear - passenger side rear inner tire, Left outer rear - driver side rear outer tire, Left inner rear - driver side rear inner tire.
Remove the valve cap from the valve stem on the left front tire. Decrease the air pressure until the horn sounds.
Note: The single horn chirp confirms that the sensor identification code has been learned by the module for this position. If a double horn is heard, the reset procedure was unsuccessful, and you must repeat it.
Remove the valve cap from the valve stem on the right front tire. Decrease the air pressure until the horn sounds.
Remove the valve cap from the valve stem on the right outer rear tire. Decrease the air pressure until the horn sounds.
