Volvo Penta key/ Manuals

Many of the "manuals" are available online, but those that are free are usually just basic owners manuals as opposed to a proper workshop manual. Avoid a site called "manuals lib online" or some such name, as it appears from experience to be a bit bogus, as I've gotten warning messages from my security software, suggesting that it attempted to download malware.
Regarding the key, I have a pair of volvo ignition switches, with keys, if you don't have any joy sorting out a key. If you're based in Dublin, there's a company called key one, right beside Newlands Cross on the Naas Road. They did me a copy of a keyless entry key fob at an excellent price. They also cut every sort of key. Might be worth a phone call.
