The battery arrived after a very short waiting time, here kudos to the shipper. I had to for the central locking my car change the battery of my key transmitter and have bought later with this order exactly what was originally inserted in the key transmitter. I do not know what it was, but this battery has only held one week. Have often read like, but wanted to convince myself. As such, the battery is fine and does what it should, but I do not recommend the use of remote controls.
