Can't open the driver's door manually? 

It is possible that the driver's door may not open with the key. If that is the case, try the following: 

  1. Get a can of spray penetrating rust lubricant and spray in the keyhole. 
  2. Insert the key in and out a few times to loosen up the key tumbler. 
  3. Try to unlock the driver's door. 

If the procedure above does not work, call a locksmith to come out and unlock the door. 

Also, check the clamps on the battery terminal. If they aren't making good contact, the Acura will make a clicking noise when trying to start the engine.
