I have a 98 saturn sl2. First is the dome light does not work, second is the door locks from the remote key pad work, ( lock and unlock ), but the manual lock and unlock buttons on the car doors will not work. any ideas?

Try this please!
'98 - '02 Isuzu Rodeo and Trooper and Honda Passport(with factory keyless entry) Instructions for programming. 1. Get in car and make sure all doors are unlocked. 2. Open driver's door and leave open. 3. Put key in ignition. 4. Turn key to 'on position' (dash lights on, but do not start) and back to 'off position' 3 times in 5 seconds or less. (you must turn the key very fast) 5. Close and open driver's door 2 times in 5 seconds or less. 6. Turn key to 'on position' and back to 'off position' 5 times in 5 seconds or less. (turn key very fast) 7. Close and open driver's door the doors should lock and unlock twice after this happens push the lock or unlock button on the remote, doors will lock and unlock. Push the lock or unlock button a second time and doors will lock and unlock again. You are finished! The above sequence erases all previous codes and adds the new code as #1. If you are adding a second remote, you should follow the same sequence with the exception of step 6; instead of turning the key to the 'on position' and back to the 'off position' 5 times in 5 seconds or less, do it 3 times in 5 seconds or less and then continue to step 7. ***Remember to turn the key to the on and off position very fast. This works! Follow directions EXACTLY. I had to try 3-4 times before getting it to work. I failed to go exactly by the instructions the first few times.

have you checked the fuzes ?

FORD KEY PADS

• Enter permanent factory code
  
• Press the 1/2 button within 5 seconds to enter programming mode
  
• Within 5 seconds enter new code, doors will lock, unlock to verify code, this erases previous codes remotes will also need to be programmed. (MAYBE)
  

KEY PADS/REMOTES

• Insert key, turn ignition off-to- on eight times in succession, ending with key in on position doors will lock, unlock to verify in programming mode
  
• Press any button on new remote, doors will lock, unlock to verify
  
• Do the previous step with the second remote, doors will lock unlock to verify.
  
• Turn ignition off. Doors will again lock, unlock to verify.
  

NOTE-Some vehicles use 5 turns of the key instead of 8

I had this same exact problem in a family member's Saturn. If you are opening the door with the key and not using the key FOB to unlock the doors, then the security system will not allow you to start the car. You will notice when this happens that the dome light will blink and you'll hear the relay in the BCM clicking.

In order to stop the security system from doing this: Make sure the car is locked with the key fob by hitting the lock button. Then hit the unlock button on the key fob once and then once again (I do it out of habit). Then open the driver side door, put the key in and it should start no problem.

there should be a security box in the left rear seat behind the paneling,,,that controls all that` stuff that masy be your problem

You need to program the system,it's probally in theft deterrent mode & disables the starter.To program your new remote locate the diagnostic connector under the drivers side of dash.To program the new remote Jumper a paper clip between the #4 & #8 terminal you will hear the locks cycle & the trunk will pop.While the terminalsv are jumped hold down lock & Unlock on the remote at the same time until you hear the locks cycle again,remove the jumper wire or paper clip & you should be good.

check your fuses, quite a big one considering it supplies all your locks

What fuse did you check ? 10amp body fuse in the I/P fuse box . Check for B+ voltage ,with a volt meter , on both sides of the fuse . Black lead to ground an touch the little metal tab's on top of the fuse one at a time . Should see battery voltage with the door open . If there is no voltage check the 30 amp batt fuse in the I/P fuse box . For the power locks did you check 20amp locks fuse located in the I/P fuse box ?

open the fuse box on the passenger side of the console. Check all the fuses. Also there is a fuse box under the hood I believe on the driver side. check all these fuses also. The only other thing to check if your motors are working fine, is the wiring.
