Oh hey my driver suggested a nice idea too.
He said go for an alarm system which will have a separate remote and the original key can be used as is. So I went over to a few stores and found something even more intriguing.
It was an alarm with 2 Toyota keys with built in transmitters & Panic feature.Actually I held the key in my palm and it was way better quality (plastic), and there would be 2. He also happened to be an old friend of my driver and offered a price, 3000rs + installation & a 5 yr warranty. I really liked this as there would now be 2 remotes.
I did some research and talked to my dad, he said that installing this "new" receiver/transmitter would greatly reduced the pre-built safety and security with regard to door locks as comparing with the standard system by Toyota. He says a "cheap" alarm system & remote would be easy to hack for thieves and the car would be easy to steal. True?
