Key Remote?

I bought a new 2011 Camry with central locking system but without a remote control for that. I would like to install one. Can I do it myself, will this void my warranty?

The remote trunk release in cabin will not release the rear trunk. The cable pull the mechanism that has a rod to the trunk lock, however the rod does not move to release the lock. What part of mechanism is broken? Or spring missing? That prevents the release of trunk lock?

The key will release the lock, when inserted in the lock. The key remote will release the lock. The release lever inside the car is the non-working part. The lever has a cable, this move the release mechanism, which has a bar going to the truck lock, but the bar does not pull the lock to cause release. Question: Does repair manual show this assy? It is attached to trunk lid, and not to trunk lock. Connection from release to lock is by means of a bar.

Found the problem. Fixed

Remotes no longer open or closes locks. Batteries replaced?

My 2005 Camry xle has a power unlock problem for the three non driver doors only when it is warm outside like over about 70. I replaced the master switch on the driver door and same thing. With the remote (factory) it acts the same way however it always "locks" all 4 doors fine from either the remote fob and the driver switch. The problem is only the power "unlock" for the three non driver doors when it is warm out.

I was given the car listed above that was a friend's father in law. About two years ago the car was pulled underneath a carport and set on blocks so the old man could not drive it. The car ran fine when it was pulled in there. In trying to prepare the car for the road I put a new battery in it I put my negative on first and when I put the touched the positive to the post and it automatically start to turn the car over. I had the keys in my hand and we are not cable touch that post it started my car and I cannot get it off of that remote start to where the key works in order for it to turn the car off using the key. Like I said I can get the car started but only when the post hits the post. The car will not turn off. The key is useless. It is stuck in remote start mode or something. Can you give me anything on this? Thank you
I have two remote start fobs and a key with its standard key fob.

I recently bought the car listed above LE model. The engine was replaced in it and it did not come with a key fob so I have bought three different key fobs including a Toyota key fob and none of them will work. I follow instructions and locks do not respond to any of the instructions. Keep in mind I know nothing about cars. Is it possible that the receiver is disconnected or bad and where is it located on the car? I am at the point of taking it to the Toyota dealership and seeing if they can fix it, knowing it is going to cost a lot. If someone could help I would be greatful.

I have 3 remote controls, none of which work. They are the same, and were purchased from the dealer to replace the originals. The FCC ID # IS JDRAPSBT, one button, for l995 Toyota Camry. The car was ordered from Japan with the remote control, but the dealers may have installed it.
The remotes are clean, air cleaned, new [tested]batteries installed. The light comes on when the button is depressed on all of them but the car doors do not open so it is not responding. It was working when I first got them. Could it be that the programing in he car was effected when a new battery was purchased? Can you give me instructions to program it to work? I do not want to do it at the dealers as they charge a great deal per remote to program it. Please help.
Thanking you.
