Will disconnected car battery erase keyless drive data?

[jaswane]

Hi!

I'm in the progress of changing the Bi-Xenon bulbs on my Volvo V50, 1.6d, 2009 model.

To do that I'll have to disconnect the battery on the car due to high voltage.

My question is: Will I erase the keyless drive data in the car when I disconnect the battery, leaving the car with no power for a while? I have heard about expensive reprogramming of keyless car keys after flat battery etc.

Thanks for any advice.

No there is no problem in disconnecting the battery , all you loose is the time from the clock ..
