Paint scraper or chisel can work. If the putty is hard to remove, you could use a heat gun to soften it. Hold the heat gun about 1 inch away from the glass and move it around to spread the heat. Double-up the aluminum foil and place it on the panes that are next to it. This will prevent them from breaking due to heat.
After removing the old glass, take a damp cloth and clean the inside of the window sash in order to remove any dirt or dust. Then, you can put in a new pane of glass.
To cut a glass piece to size first, take measurements of the width and height of the existing opening. Take these measurements and subtract 1/8 inch from all sides to create a new piece that will fit easily into the door frame. Many hardware stores will cut a piece of glass for you in the event that they have the measurements.
Warm up a handful of putty and then roll it into a 3/4-inch thick rope. Place the putty on the edge of the exposed rabbet. Then, rest the blade of your putty knife at a 45 degree angle against the frame rabbet. The knife should be pulled along the edge of the glass in a smooth, straight line to cut a piece of the pane.

Installing the new glass is easy after the molding is removed. Visit a glass store and measure the glass's opening. It is a good idea to get a piece of safety glass, as it won't break as easily should your French doors break again.
When you are ready to put your glass piece in the opening, make sure that it is aligned properly. Apply a thin layer clear silicone caulk to the edges of the glass.
Once the caulk has dried it is possible to replace the molding. If the nails that were originally used didn't pull through the molding, you can put new wire nails into the holes created by the old nails. To avoid the nails cutting the molding, you must drill the holes prior to drilling them. A well-stocked hardware store has very thin bits that you can use to drill holes.
How to Cut a New Pane Of Glass
Check the spacing around the frame of the window as well as the edges prior to ordering a replacement pane. If you notice any gaps, you might require adjusting the spring clips or triangles that hold it in place. You should also make sure that the new pane is the right size for the opening. If it's too big there could be leaks or other issues.
The first step is to create a work surface. With a putty knife scrape away the old compound on both sides of the frame. This will expose bare wood. If the rabbets are too rough for you to smooth with the putty knife then lightly sand them, and apply an exterior primer. This will stop the new glaze from absorbing moisture from the wood, which will reduce its life span.
Once the frame has been cleaned and prepared, rub some putty until it is soft and malleable. Use the putty knife apply a thin layer of it to the inside corner of the rabbets. This creates an elongated bed for the glass to rest on. Repeat the process for the other edges that are exposed on the rabbets.
Remove any remaining metal pieces from the grooves of the sash after the putty has dried. Before you attempt to remove them, put on a pair of safety goggles to protect yourself from glass shattering. Heat guns on low settings can be used to gently warm the metal and loosen it up so you can take it off with pliers.
Place the glass in place to test fit. Make any necessary adjustments prior to attaching it to the frame using the spring clips or metal triangles. Make sure the gap between the frame and the glass is even across all sides. Examine the movement of the window sash, and make sure that the new glass does not interfere with the closing or opening.

This will also allow for seasonal expansion and contraction of the wood frame. Bring your measurements to a hardware store or home center, and let them cut a piece of glass for you. You can cut the glass yourself, when you have a large sheet on hand.
After the old pane of glass is removed, you must clean out the window sash grooves, and remove any glazing points made of steel that held the old pane in place. A pull-type paint scraper or a chisel will work to accomplish this job. If the grooves are filled of putty that has hardened, slowly soften it with a heat gun. Be sure to cover windows and moldings with aluminum foil to shield them from the heat.
You can also apply an exterior primer to prevent the putty from absorbing its natural oils. You should also wipe down the sash to get rid of dust and dirt from the grooves.
Knead a small amount of putty until it's warm and flexible, then press it into the rabbets, where the glass will go. The appearance of the glass isn't crucial at this stage. Press the new pane in the rabbets and then move it using your fingers.
Fill any holes in the frame with silicone caulk. Then, you can install the new glass. If the frame has any other mechanisms for fastening like L-channels for example, make use of a hammer to pull them out of the sash grooves. Take out any shards of wood that might have come loose in the removal of the frame.
