Just curiously about if I disconnect battery..will it reset the stock alarm and evrything else and you gotta reset it back????....I brought optima yellow and want to change it.....I dunno about reenter the code and stuff and dont want to ruin it....Thankz

 

you'll need to re-enter the radio code and you'll loose all your radio station presets. Alarm will not be affected, unless you have an aftermarket alarm with backup horn

 

Thankz Steve...so as you said it wont do anything to Alarm or the engine code that wont let you start up car right???....where do I find the radio code anyway ??....Congrat on ur Wedd

 

Your radio code should be on a business-type card..

 

Yup, just your radio code and navi code if the battery has been diconnecting long enough. Also your radio presets, everything else will remain in tact. I have both codes saves as text messages in my phone, with the amount of disconnecting the battery I do, it just seemed like the best solution.
