This silicone rubber fits Many Toyota car remotes like a glove(both2 and 3 botton remotes) Please take a close look and make sure picture resembles your remote.
Works for 2002 Camry -2006, Corolla. Highlander, 4runner and others of right around the same period. It prevents the little tip through which the key ring goes through from breaking off. Even when the tip is broken off, this rubber covers up the damage and still holds the key ring in place.
Your remote bottons never get damaged and the whole unit lasts much longer.
