I've checked the battery every day since I started this post and not recorded a voltage lower than 11.7v. Would 8v destroy the key coding as suggested by COLVERT?

NO.--It's not the low voltage but the sudden surges of voltage that does the harm.---They are called SPIKES in the trade. Voltages can be generated much, much higher than the battery12 volts.--( into hundreds. ) |
