Door Lock Issue
Looking for advice and hoping to avoid dealer repair....from time to time my back doors won't lock or unlock using the remote. The dealer is suggesting a complete actuator replacement, but I've read that a replacement motor can also be purchased for far cheaper. Part # or suggestions on where to find would be appreciated! Thanks

JCG has a good point. Is the problem only with the remote? How about the lock switch on the drivers door? Is it possible the child locks on the back doors get turned on/off at times?

If your door lock isn't opening, start by ensuring you're using the correct key, as similar keys can easily be mistaken. If the key is correct, inspect it for damage or wear. If the key appears fine, try lubricating the lock. A dry lock can often be the cause of a key not turning smoothly. Use a graphite-based lubricant or a silicone-based lubricant; avoid oil-based products as they can attract dirt. If the key turns but the lock doesn't open, the issue might be with the lock mechanism. In this case, you might need to jiggle the key gently while trying to turn it. If the key doesn't turn at all, check if the lock is frozen (common in cold weather) and use a de-icer or a hairdryer to thaw it. If these steps don't work, the lock might be broken or the key may be worn out, and it may be time to contact a locksmith for professional help. Remember, forcing the key can cause it to break inside the lock, complicating the situation.
