Thanks for all the info and suggestions and yes it is Keyless entry.
I contacted Volvo assist number you supplied and they talked me through some things BUT the only key slot is on the passenger door (lift and it’s under the handle) and sure as eggs are eggs in the 4 years we have had it , it had ‘seized’ and would not open! Even our petrolhead neighbour tried and failed.
We sit, thankfully at home waiting Rachel Thieves at the despatch box and a Volvo technician to arrive - a knight in shining armour to rescue us……….
Just as an aside I have been reading about peoples Morgan battery issues - gosh that seems like a real faff. When did life get so complex . The Victorians built stuff that lasts, hospitals, steam engines, sewers…..now you have to routinely manage your new kitchen and stone surfaces with special cleaners. Service your boiler annually - the last gas one went for 34 years without a service,, this one has an outdoor condensing pipe from the cellar that frozen up when cold. Just when we needed the heat.
I could be Grumpy Pa if it hadn’t been used already ! I get grumpier by the week and todays budget will make me worse.
Anyway much appreciated your comments and assistance . MM
