Ph1 dropped key now central locking not working

Ok before i assume the obvious.....
I dropped my key tonight now the central locking doesnt work. Fortunately the car starts fine.

I assume there is no cheap or simple fix other than a new key???

Any suggestions for cheapest ph1 key?

@Mike@Rentech?

It should be easy to fix. take the battery cover off and look on the circuit board. there is a little push switch that has 4 legs that solder to the board. I bet one of these legs has come loose. get a soldering iron on it and solder it back. should be really easy. It has happened to me before.

Just had a look.... The circuit board seems part of the lid with just a metal tab bent down to connect to the battery, i dont see anything with 4 Legs to solder?

Oh, not the same as a mk2 key then. under the unlock button there is a microswitch , check the solder on that.
