Unless you have a TPMS programmer, you might want to buy all 4, because the dealer will charge you to get the system to talk to the new sensors.
If one failed, the others are likely to follow suit.
You can probably get a better deal at a tire store than the dealer - some tire stores will replace sensors - I know Discount tire does.
Replacing the sensors means the tires will need to be dismounted / tpms installed / remounted / rebalanced.
If you are coming due for tires, you might want to wait until you need the tires replaced so you don't have the additional expense.
