The instructions on replacing the battery in the key is there. If you don't it's as simple as removing one screw. Opening the housing, and replacing the battery with a similar one. Take note though on how the battery is placed into the key.
What do you mean, "sumasablay minsan ung power lock ko sa drivers side na window."
Signal light switch? Combo switch ito. What problems are you encountering with it? Is it the switch or the Flasher? Please describe it in detail. Signal lights light up? Indicator sa instrument panel lights up? or basta walang ilaw at tunog?
Odo/Speedo - better bring it to the casa to check for the DTC (Diagnostic Trouble Codes) This one needs a Scan Tool.
