door lock sticking and '06 eating aftermarket headlight replacements???

Couple questions? First, passenger door locks are sticking. Are there any maintenance options on door lock actuators or is it a modular just buy a new one replacement thing? Best place to buy replacements?

Second, Factory headlights worked for 1.5 years and every brand I have tried to replace them with lasts only 3-5 months. I've tried 3-4 different brands from cheap to expensive and taken all the necessary precautions when handling the bulbs. Any thoughts?

When you replace your bulbs you need to wear gloves, headlights burn hot and the oils from your hands will harm your new bulbs and lessen the life of them.
