SOURCE: replacing the 1,1 oxygen sensor
P0134 means that no activitiy (function) is detected in the sensor. P0135 is an 02 sensor heater malfunction. Basically, it sounds as if your O2 sensor is dead and needs replacement. Being that you state it's the 1,1 sensor, you're talking about the primary, or pre-catalyst, oxygen sensor. This is the one closest to the engine, before the catalytic converter.

Both my remotes no longer work. I will be ordering new ones off Ebay and having my dealer program them. New ones from Buick are very pricey.

Given that most of the trouble codes are for the O2 sensor, I think I would change it. The multiple misfires could be because of improper fuel/air mixture caused by a bad sensor. Disconnect the negative(-) battery terminal then change the sensor. Disconnecting the negative(-) should reset the computer and allow the fuel/air mixture to return to default allowing the engine to start.
P0130 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0134 - O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
