Model: Honda Forza 125
Part: Battery

Replacing the battery on the Forza 125 with Keyless Go system requires attention, as if the battery is flat, the seat will not open electronically. To access it, remove the left side panel and, using the supplied hex key, turn the emergency release lock under the seat. The battery is located under the seat. Disconnect the negative terminal first, then the positive. Remove the old battery and install the new one. (You can find it on eBay with code 395029938639 for £31.50 + £5.00 shipping). Before restarting, the Keyless Go system must be reprogrammed: using the security key (blue) and the coding device (red), enter the 5-digit code (found on the sticker) within 5 seconds of turning on. Press the ignition button the number of times corresponding to each digit, waiting for a flash between each digit. Once completed, the seat will unlock and the system will reactivate.
