2014 IS-250 Remote Start with Factory keypad integration
1. There have been documented issues with the Lock-Unlock-Lock option compared to the default Lock-Lock-Lock button sequence. This is related to how the module syncs with the vehicle to know which was the last lock/unlock command received. (e.g. using the door handle with the key in proximity mode counts as unlock but so does pressing the unlock on the remote).
2. In the wiring diagram posted above from the manufacturer, a physical tap into the parking lights is required for the module to activate exterior lights when remotely started. Therefore, if the module were to malfunction, the headlights, taillights, etc. would not operate. I opted to not connect the parking lights for this reason. (i.e. no exterior lights are on when the vehicle is remotely started).
3. If the parking lights are wired to the module, there is no way for the parking lights to shut off when the timer for the remote start has elapsed if the the headlamp switch is left in AUTO. The module must bypass the factory battery saver function so until a door is opened and closed, the lights will remain on leading to battery drain.
4. Secure takeover is not supported. (i.e. When you open the doors, the engine will shut off. Opening the truck however, will not shut off the engine.)
I had the module installed for sub $400, so it's quite affordable. The most important item for me was having a no-fuss system without having to lug around another remote and this fit the bill perfectly. Range was not an issue for me since it's parked in the garage at home or near a window at work. If you get the RS-TL7 firmware, the module can support an aftermarket system should you opt for a later upgrade.
Kudos to Ultimate Sound Connection in Edmonton for the excellent service.
It cost about $130-150 online, there are three types: continental USA, Canada, and Alaska (different network carriers). It's a very easy install into the ADS-ALCA, but has a slightly complex activation sequence, which is required to turn on the SIM card and allow you to connect to the drone via app, you also have to be there for that part (to register the drone to your phone app) if you're having it done professionally.

My car's exterior lights do not turn on when the remote start activates, but they do flash when I use the Drone to lock/unlock the car, which it uses the ALCA to do. I leave my lights on auto and nothing turns on with remote start so I guess I don't have to worry about battery drain.
