Hi, my 2022 nmax 125cc sgcu stopped working and the mechanic said it will take 5 month for a new one to come in and will cost me £500. I found the exact one on eBay for £100 with the same code and numbers. Can I just simply put that on my bike and use my key? I asked around and I was told the cdi unit (which handles the keyless entry) is not coded to the sgcu? Anyone that could help would be appreciated.
