This topic should provide detailed information on TPMS as installed on the 9th gen Civic, and is meant as a reference.
What is TPMS?
TPMS stands for Tire Pressure Monitoring System. When your tire pressure falls below a threshold, either due to a slow leak or just atmospheric changes (1 psi drop for every 10 degrees F less), then the TPMS pressure warning light will activate. When TPMS detects this condition, you will NOT be able to shut off VSA (Vehicle Stability Assist). Altering the TPMS system either by pulling the TPMS fuse, or having no TPMS sensors, will cause TPMS to detect a system fault, display a warning light, and you will NOT be able to shut off VSA either (this has been tested/verified on our cars by nateg20).
TPMS is mandated in the US today (TREAD Act) as of 2008, and was a result of the NHTSA investigations into Ford Explorer rollovers. It will be mandatory in the EU by the end of 2012.
Can I ignore the TPMS light/warnings?
You can do this but you will NOT be able to disable VSA. This will mean that the car will constantly cut power if the tires slip, thus in slippery wet/ice/snow conditions, your car will get stuck. Also if you are driving on a track, you cannot disable the stability assist, which will start to interfere with performance driving. So like it or not, TPMS is something we have to deal with.
How To Reprogram TPMS Sensor IDs
In order to reprogram your TPMS sensor IDs, you will need a tool that can connect to the OBDII port in your car. You will need to know the TPMS sensor IDs to do this. Normally this is done by a dealer using the HDS (Honda Diagnostic System), but some tools are available for DIY.
ATEQ TPMS QuickSet - relatively, only can re-program sensor IDs via OBDII port.
ATEQ VT55 OBDII - pricey, full featured TPMS tool, sensor activation, ID learning and OBDII re-program.
Note, online vendors such as Tire Rack offer OEM equivalent TPMS sensors, but due to activation issues by people attempting DIY, they ship them "un-activated" now. The TPMS sensor will need an activation signal to wake it up from sleep, which is something the QuickSet tool can't do. Also even if they give you the new sensor IDs, it is possible that they might mistype/misrecord this information. So if you have new sensors, unless you have the pricey VT55, you will also need...
ATEQ VT15 - sensor activation/triggering only.
ATEQ VT30 - sensor activation/triggering, and sensor ID decoding.
For the price, I would go for the VT30 with the QuickSet if you intend to DIY the whole process. You could possibly sell off the VT30, since all you will need is the QuickSet to swap between two sets of activated sensors on two different sets of wheels (eg. summer/winter). The other vendor of TPMS tools is Bartec...

Can I clone the original sensor IDs?
Bartec also offers programmable sensors that can "clone" your current sensor IDs, which is more flexible, but it requires access to the right tools. You can get it from Discount Tire, but they cannot learn/re-program sensors for online orders, you have to take your car into a shop with the right tools to program those sensors, to make them work right.
Can the dealer re-progam TPMS for me?
Re-programming at the Honda dealer is done via the combination of the HDS to hook up to the OBDII, and the VT55 tool (you can see this in the PDF directions for installation of HFP wheels which come with new TPMS sensors). Costs vary - mine wants $110 to do this! And if you are swapping tires out each season, that's 2x a year you'll be paying for that.

There is one additional thing your dealer can do with the HDS... they can re-program the TPMS threshold (ie. when TPMS gets triggered). Not sure how many dealers are willing to do this, but if you need to run low pressures intentionally ie. track, then this is the only option you have to get the threshold lower than the usual setting (somewhere about 5 psi below recommended should trigger TPMS).
Additional Notes
Note - the deflation/inflation to trigger a sensor won't work on new, previously un-activated sensors. These need the trigger radio signal to be sent to them at least once, to wake them up from the factory sleep mode (done to conserve the battery in new sensors). And yes - someday the battery will die and sensors have to be replaced, this could be in 8-10 years.
Updates
It looks like deflating/reinflating can be used to activate new TPMS sensors as reported by some others. I haven't tried this myself but its definitely worth a try especially if you know the sensor IDs and just want to use the Quickset by itself.
Also 2014 Civics and various other Hondas are don't use sensors anymore, they use ABS sensors which require calibration, but this can be done pretty easily now. I'm not sure if 2013s have this, but us with 2012s are stuck with the TPMS sensors.
Note - I haven't been active much here for a while so haven't kept this fully updated, so be sure to check out what others are reporting as well on the topic.
