Signs of a Failing Door Lock
After decades of use, the door locks on your 1987 V1500 will inevitably wear out. The symptoms are usually straightforward and mechanical. You might find the key is difficult to insert or turn, or it gets stuck in the cylinder. The lock might feel loose and wobbly, indicating worn internal tumblers. Eventually, the lock may fail to engage or disengage entirely, preventing you from securing your truck or getting inside.
Choosing Your Replacement: Aftermarket is the Smart Choice
Finding a brand-new Original Equipment (OEM) door lock kit from GM for a 1987 truck is highly unlikely. Your options are typically used parts from a salvage yard or new aftermarket kits.
- Used OEM: While an option, you are buying a part that is just as old as the one that failed. It may have significant wear and may not come with keys.
- New Aftermarket: This is the most practical and reliable solution. Aftermarket brands produce new parts that meet original specifications. For a simple mechanical part like a door lock cylinder, a quality aftermarket kit provides a fresh start with new cylinders and keys, ensuring smooth operation.
Standard Ignition is a well-regarded brand in the aftermarket industry, known for producing quality components that are engineered to be direct-fit replacements. For a V1500, their door lock kits are a dependable choice for restoring proper function and security.

Frequently Asked Questions
Is replacing a door lock kit a good DIY project?
Yes, for most owners with basic hand tools. The process involves removing the interior door panel, releasing a retaining clip, disconnecting the lock rod, and swapping the cylinder. It's a manageable job that typically takes one to two hours.
Do aftermarket kits come with new keys?
Yes, new door lock kits come as a set with two new lock cylinders and a matching pair of keys. This ensures both doors operate with the same key.
Are the driver and passenger side locks different?
The lock cylinders themselves are often identical, but the small pawl or lever on the back may need to be oriented differently for the driver and passenger side. Some kits come with separate pawls. Pay close attention to how the old one comes off.
Should I lubricate the new locks?
It's a good practice to apply a small amount of graphite lubricant to the new lock cylinders. Avoid using oil-based sprays like WD-40, as they can attract dirt and gum up the lock mechanism over time.
Are there any recalls for 1987 GMC V1500 door locks?
No, a search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls specifically for the door lock cylinders on this vehicle. Any issues are due to normal wear and tear over time.
