Two out of my two vehicles have blinking tire pressure lights. 06 gs300, and a 05 Sequoia. Is there a way to tell which ones are bad without going to a dealer?

Go to any tire shop.
Assume you did check the presssures.
In reply to iceracer :
Blinking means issue with a sensor. Staying on means tire pressure.
Somebody has to say it...
Electrical tape over the blinking light?
In reply to BoxheadTim :
That would work for most cars. For the Lexus, the tire light blinks, the warning light stays on, and this message won't go away.
Because a tire sensor is that big of a deal, I need two lights and a giant ass warning message.
I bought a "Wells" tpms sensor programmer and reader from AutoZone when they had online coupons.
Essentially the programmer can read most tpms sensors, and can program Wells brand replacement sensors. Mine can't reprogram the car side, but it doesn't need to if you "clone" the old sensor as the car sees the same id.
It wasn't cheap, but it cost about the same as having a dealer diagnose and replace the sensors. The Wells sensors are cheaper than the OEM sensors.
I took the valve cores out, broke the tire bead on the valve side and replaced 4 Honda sensors without dismounting and rebalancing the tires.
The cheaper options are to get aftermarket tpms sensors and a cheap "car programmer" to reset your car to look for the new sensors you put in. I didn't try this option as I was hesitant of the longevity of the no name brand sensors and the 'one make' specific car reprogramming techniques.
The Wells programmer "Wells tpms2" can read sensors by being held in the proximity of the sensor of many different makes. I diagnosed a bad sensor as it would not read the dead sensor. I was able to clone the replacement from the I'd printed on the broken sensor.
Now I have the tool it's easy to swap sensors other than the labor of breaking the tire bead and holding the tire away from the sensor.
OK, so I now have one vehicle with these sensor thingies. I put snows on with new O'Reilley sensors. I think they were Standard brand. Of course, the TPMS light is on. How do I fix this? Do I need one of these programmer thingies to copy the ID from my Land Rover branded sensors in the non-snow tires and clone the Standard sensors?

What kind of car do you have.
This is depressingly unstandardized Some cars, like Ford and for some damn reason many Hyundai/Kia (by probability, they had to eventually get SOMETHING right), they recognize new sensors within a block or two.
Other times, like some other Hyundai/Kia, if you don't have OEM sensors, you are berked.
The 90% of the time in the middle, the sensors need to be programmed, and/or the vehicle needs to be told which sensor IDs to pay attention to. This process is called "relearning" and makes the grammar portion of my brain twitch like a frog leg hooked up to 110VAC.

2011 Land Rover LR2. Land Rover looks to do a lot of things "only at the dealer." Like programming a key, for example. On a Lexus, you do this dance around the vehicle, chanting "Toy-Yo-Da" while rubbing your belly and patting your head and it will recognize the new key. Land Rover? Go to the dealer. Even the aftermarket full-access (sort of) interfaces won't do it.
I'll look into it. BUT, just to clarify some things:
Sensors can generally only be programmed with an ID once. I say "generally" because this is the way every programmable sensor I've worked with has worked, but there may be things I don't know about yet.
If you buy a "drop in" sensor that does not need to be programmed, they must be relearned (twitch, twitch) to the car. You can't clone your old sensors, since they already have an ID programmed into them.
If you buy a blank sensor that needs to be programmed, you can clone your old sensors. Or you can have your sensor programming tool make up a random sensor ID and program that in. Either way you can't just put them in and expect them to work, they have no ID in them until a programming tool gives it one.
OK, I see. I bought 4 new ones, had them put in when the tires were mounted on my new wheels. So, I assume they are unprogrammed. There were, of course, not instructions in the boxes. If I had one of those tools, I could "read" the sensor on one of my old wheels, then go and program the sensor on the new wheel to be the same?
In reply to Dr. Hess :
Assuming that you installed blank sensors, yes. Programming an already mounted sensor/tire combo can be hit or miss, due to tire interference.
One gotcha I learned in the "made a brick" way is that when cloning sensors, do one sensor at a time at least 10 feet from the other sensors. The tool read the same sensor twice because it was already "woken up".
OK. I'm thinking of this one:

Seems to be well regarded.
