Hi Sean,
99% of vehicles that require a key to start the vehicle will not be covered by the EVO-ALL to do stand alone. A seperate remote starter unit is required in order to power up ignition/accessory/start.
Here's a list of vehicles compatible with the EVO-ALL stand alone feature. http://fortin.ca/en/features/3x_lock_remote_starter.html
It still would be possible to use the OEM remote though with remote starters. There is another feature called OEM Remote Monitoring in the EVO-ALL. With datalink compatible remote starters and on vehicles that we offer the OEM Remote Monitoring feature, you would be able yo use the OEM remote to start the car.
Here is a list of vehicles we currently can offer OEM Remote Monitoring : http://fortin.ca/en/features/oem_remote_monitoring.html
In cars that we do not offer OEM remote monitoring or Stand Alone remote start, it's still possible to start the car using the OEM remote! A lot of remote starters come with a programmable external trigger input wire. This wire is normally wired to the vehicles lock wire and programmed to check for 3 pulses. The trigger wire starts and stops the remote starter.
For this particular 2007 Camry, we only offer transponder bypass.
Take a look at this 2010 Camry. Under the built in functions section, Stand Alone Remote Starter is not listed therefore a remote starter is required for this car. If you scroll down a bit, you will that a feature called OEM Remote Monitoring is offered. In this case, if you wanted to use the OEM remote to start the car, it would be possible but since we do not offer Stand Alone Remote Starter, an actual remote starter brain is required.
Hope this makes some sense..
