lock problem

Friends, my car was lying for 15 days, the battery is dead. The central lock does not work due to the key, the tongue does not open the doors with brakes. I do not have the possibility to open the hood. 2001 model 306

The same situation that had happened to me in the company car was Wolksvagen Passat 2001 model, I went to the mechanic, the man managed to lift the car and go under the barriers and connect the reinforcement cable to the battery and we were able to open the car.
