no, you just need to ONLY replace the cylinder and if the new key has a chip in it get a copy made and use that one with your old master key held next to it to start the car.

Hi have you checked the brake fluid level ?

2004 Honda Civic | Answered on Oct 07, 2017 | 75 views

First things I would look at is,did they put 10w30 oil in and not 5w20 or 0w20,it makes a difference in mileage (if they run out of the correct viscosity oil they WILL put in what they have).
Did the service include a spark plug change?Is the spark plug gap correct?
Did they do a brake service?Is a brake dragging,a little to tight?Did they clean the throttle body?Maybe the engine was running a little lean before and now is at the proper fuel mixture,with less MPGs but running clean at the exhaust.
Weather conditions?Head winds and colder temps reduce MPG.

not normally as it is in the timing cover case or behind the bottom sprocket or drive pullet for the timing belt
if it is a rear main seal it will require the transmission removal as well as the flywheel /torque converter
you were not specific as to which oil seal required replacing.
best get a workshop manual as that book shows the procedure to replace seals

I think it is only a battery problem. Normally this happens rarely but i think it is a defected battery.

I would have it tested with a gas meter to see if the head gasket is leaking, I bet it is.

Tune up the car with the following items included:
- Clean the throttle body and free up the idle air control valve.
- Adjust the valve clearance according to the manufacture's specifications.
- Adjust the spark plug gaps to the standard.
- Clean or replace element air cleaner.
- Re-learn the idle speed.

My Taurus wagon had same thing once. It was a TFI sensor(for fuel injector's) on the outside of the distributer. Maybe you have something similar on the Honda. Could be timing belt also. Engine won't engage if it does not have a belt or chain in tact. Toyota Rav 4 had that. Did same thing you describe.
