My keyless entry system is starting to not respond to the remote (OEM) on the and used to not even respond unless it was like right next to it.
What are the alternatives to the stock remote and will they increase range?

I have read here that keylessride.com makes a transmitter for us, but I would like to know if it increased range or responsiveness at all. Can we also install viper alarms or other security systems like that instead to get better response for the keyless?

Also, what can i do if the door to the radio just flops down. I read there was a gear or something there that would let it down slowly, so i assume mine broke. How much and what kind of work will it require to repair this?

Thanks
