I have a 98' Avenger and the remote "unlock" button is a hassle to get to open. I have to push it all the way down and at an angle to get it to unlock the doors. I dont mind having to walk over to the car and unlock the door but I wanted to know if there was anywhere or any way I could fix the remote.

Its been a while, but the 'Lock' and 'Panic' button work fine, thats what throws me off.

yeah, you can take it apart and should be able to remove the rubber buttons and put them back. Sometimes, the buttons can get a little dirty if you have a habit of storing your keys in dirty areas or if someone generously gave your keychain some coke or pepsi. Try using something [that has a non sharp point] to gently push the button down once you have the case open. if you don't have any problems locking and unlocking the car, it's the buttons/top part of the case needing to be cleaned. If you still have problems with the response, definitely replace the battery.
