Toyota Camry 2.2litre automatic speedometer not working, driving with one gear till revs are too high

If you are referring to the vehicle having a "Timing Belt", no, it does not have one.
The 2002 Camry 4 cylinder has a Timing CHAIN, and does not need to be replaced.

Sounds like low transmission fluid to me... when was the last time you checked it?

If your remote is attached to the key in the ignition, it could have been bumped setting off the alarm. It is also possible for the lock button to be depressed and lock the doors, if you do not notice this and get out of the car........!

you didn't make clear you have a automatic trasmission or manual?
if is a manual trasmission you have to look the clutch and to valves that is puting the trasmision oil pressure to move the clutch one at the end near the gear box and the second after the clutch pedal outside of the cabin imediatley after the pedal. you have to look to the oil level in the rezervoir, if you dont have the problem to bay some oil and to change completely the oil first maybe the right solution to begin with oil change first , may be is freeze from the dirties finded in the oil pipes and valves.
if you have the automatic trasmission sorry i dont know, because the problems there are more complex.

check the fuses in your manual it will tell you which fuses are for the dash and replace them it sounds to me like they are blown! good luck
