Car key won't unlock car, but will lock and open trunk?

Car key won't unlock car, but will lock and open trunk?! Help?

Added (1). Basically my car key will not open my car currently, its a 2004 honda accord. However the key will lock the car making the locking noise and the open trunk button will work fine. When i go to press unlock it does nothing and the back headlights blink twice then stop. What in gods name is going on? It seems that the batteries are fine as the lock mechanism and trunk opening mechanism are in check.

Would you rather have a new 2015 Honda Accord Sport or a used 2010 Lexus GS350?

Since I'm going to college soon, as a graduation gift my mom gave me the option of choosing the new Honda Accord Sport or her 2010 Lexus GS350. I've driven her car a couple of times, and it's a really nice car, she bought it fully loaded with a bunch of packages and options when she got it and its, so its obviously the better car then the Accord. But the thing is, is that its used and her car has about 55k miles on it. Either way she's going to upgrade to a 2015 GS 350. She told if she were to trade it in, it would around $22k, which is pretty close to a new Accord. What would you choose?

My vehicle came out of the shop with a new issue after replacing the head gasket?

My 2000 Honda Accord LX was originally overheating so I figured the thermostat was bad. I planned on replacing it soon, however I wanted to replace the spark plugs before I did that. The vehicle had obviously overheated a lot before I bought it because the spark plug wires were melted to the engine. By the time I got all the spark plugs out one spark plugs threads ripped out of the engine. I brought it to the mechanic to fix it, and they found a lot of radiator fluid in the cyclinder. So they had to replace the head gasket and replaced the thermostat as well. However when I picked the vehicle up the vehicle was limiting at 3000RPM it was in limp mode. I brought it back and they ran a test and said the code called for a replacement of the alternator I opted to replace it myself but it still didn't fix it I brought back and they said I'd have to replace the ECU I didn't wanna spend 300 dollars on something that might not fix it. The current code I'm getting is for the Cylinder Position sensor (not a crankshaft position sensor) which is in the distributor housing so I replaced that and still didn't fix it it's been almost a year since I brought it to the mech i don't know if I can threaten a lawsuit to have them fix it since that problem wasn't there when I gave it to them or if anyone knows how to fix it also they said that my knock sensor was out so they put it back in i don't know if that is the cause or what
