Door locks and auto headlight problems

[Velocd]

I just installed the lotek pod and put in a voltmeter and a trans temp gauge. But now for some reason, when i open my door and push the lock button, it won't lock. I push the unlock and it works, but not the lock button. Also, i drove my car to a parking garage in the morning, but when i got into the garage, normally the auto sensor sense the dark and turn on the headlights, but this is not working anymore. Could there be something wrong with the relays? And if it is, is there a way to change them, without taking it into a shop or a dealer. I tried taking off the casing of the relays, but it seems impossible to do without breaking it. Any help would be great. Thanks!
