PHP код:

stock GetClosestVehicle(playerid, Float:range)
{
    new
        Float:pos[3],
        Float:distance,
        Float:precedent_distance = range +1,
        precedent;
        
    GetPlayerPos(playerid, pos[0], pos[1], pos[2]);    
        
    for(new vehicleid = 1; vehicleid < MAX_VEHICLES; vehicleid++)
    {    
        distance = GetVehicleDistanceFromPoint(vehicleid, pos[0], pos[1], pos[2]);
        if(distance <= range && distance <= precedent_distance)
        {
            precedent = vehicleid;
            precedent_distance = distance;
        }
    }
    return precedent;
} 


And for use in command :

PHP код:

CMD:unlock(playerid, params[])
{
      new vehicle = GetClosestVehicle(playerid, 3);
      if(vehicle == INVALID_VEHICLE_ID) return SCM(playerid, -1, "No vehicle at proximate");
      // Lock/Unlock your veh and the ID of car is in variable "vehicle"
      return 1;
} 


Sorry for this bad script, I'm on phone
