Tire Pressure Sensor

I put custom wheels on my 2006 Tacoma and now the tire pressure sensor indicator stays on. The installers said the factory sensors won't work. Any idea on how to turn the indicator light off?

Instructions for disabling the system are here;

I'm not sure if this is the only way to turn it off.
