Dodge Monaco Ignition Switch Guide: 1965-1978 Models
Solve starting problems and electrical issues by choosing the right ignition switch for your classic Dodge Monaco.
- The most critical step is identifying if you have a dash-mounted (1965-1969) or column-mounted (1970-1978) switch before ordering.
- Symptoms like a no-start condition or stalling can be caused by the ignition switch, not just the battery or starter.
- Standard Motor Products (SMP) is a reliable aftermarket brand for this part.
- For 1970+ models, inspect the main electrical connector for melting or heat damage when replacing the switch.
Is Your Ignition Switch Failing? Common Symptoms
A bad ignition switch in a 1965-1978 Dodge Monaco can cause confusing electrical problems. The symptoms often look like a dead battery or a bad starter, but the root cause is the switch itself. Watch for these warning signs:
- Car Won't Start: You turn the key and nothing happens. There is no clicking or cranking sound from the starter motor.
- Starts and Stalls: The engine starts but then immediately shuts off. This can happen if the switch loses connection when the key moves from the 'START' to the 'ON' position.
- Stalling While Driving: The engine may cut out unexpectedly while you are on the road, especially when hitting a bump. This is a dangerous situation caused by a momentary loss of power from a worn switch.
- Flickering Dashboard Lights: You may notice the dashboard lights flicker or accessories like the radio cut out intermittently. This points to a poor internal connection in the switch.
- Key is Hard to Turn or Gets Stuck: If the key binds, feels stiff, or won't come out of the ignition easily, the mechanical parts of the switch or the lock cylinder may be worn out.
Known Issue for 1970-1978 Models
On models with the steering column-mounted switch, the plastic (Molex) connector where the switch plugs into the main harness can overheat. Over time, high electrical current can melt the connector terminals, causing a poor connection and leading to many of the symptoms above. When replacing the switch, always inspect this connector for signs of melting, discoloration, or burnt plastic.
Choosing the Right Aftermarket Ignition Switch
For a classic vehicle like the Monaco, finding New Old Stock (NOS) or original OEM parts is nearly impossible. The aftermarket is the primary source for a new ignition switch. The most critical factor is identifying the correct switch for your car's year.
Generation Differences: Dash vs. Column
There was a major design change during this period:
- 1965-1969 Monaco: These models have a dash-mounted ignition switch. The entire switch and key cylinder are located on the dashboard.
- 1970-1978 Monaco: These models have a column-mounted ignition switch. The key and lock cylinder are on the steering column, connected to an electrical switch located further down inside the column.
You must order the part that matches your vehicle's configuration. The four products available cover these different designs and potential variations.
Brand Quality: Standard Ignition
Standard Motor Products (SMP) is a well-known and generally respected aftermarket manufacturer for American classic cars. Reviews from mechanics and DIYers often state that their parts are good quality, sometimes even being identical to the original OEM part but in a different box. For a part like the ignition switch, which is critical for reliability, Standard Ignition is considered a solid choice. Avoid their budget "T-Series" line if possible, which may have lower quality control.

Installation Tips
Replacing the ignition switch is a manageable DIY job for those with some experience. Always disconnect the battery first.
For 1965-1969 (Dash Mount): This is the simpler job. You will typically unscrew a bezel nut from the front of the dash and unplug the electrical connector from the back.
For 1970-1978 (Column Mount): This is more involved. The process requires removing the steering wheel with a puller, followed by a lock plate and turn signal components to access the switch inside the column. It requires patience and the correct tools.
Frequently Asked Questions
Were there any recalls for the Dodge Monaco ignition switch?
No. A search of the National Highway Traffic Safety Administration (NHTSA) database shows no recalls for the ignition switch on any 1965-1978 Dodge Monaco.
Is it safe to drive with a failing ignition switch?
No, it is not recommended. The risk of the engine stalling while driving, potentially in traffic or on a highway, is a serious safety hazard. A faulty switch can also leave you stranded without warning.
Why are there four different switches available for my car?
The options correspond to the major design change from a dash-mounted switch (1965-1969) to a column-mounted one (1970-1978). There can also be minor variations within those ranges, so it's important to match your exact year and model.
Can I just jiggle the key to make it work?
Jiggling the key might create a temporary connection and allow you to start the car, but it is not a fix. It confirms the switch is worn out and needs to be replaced. Relying on this trick will eventually fail, likely at the worst possible time.
Technical Specifications
The primary specification is the mounting location. Pre-1970 models use a dash-mounted switch, while 1970 and later models use a column-mounted switch. Electrical connectors and pin configurations will vary based on the year.
